3D Printed Delux iPad Stand

 Above: iPad Stand as shown from above 
Challenge: Student wanted to create a personalised iPad stand to support device use at home and in the classroom.  Student has designed a number of prints in the past and the intention was to include significant bells and whistles to improve its design and challenge the student.
Stand viewed from above
Background: A completely original design, with additional features that were not included in the iPad stands that were developed earlier in the year, the link to these on this blog is here.  The student who created this design and printed it is ten years old.
Level of Difficulty: Medium - student wanted to incorperate a design with the stand, their name, a hole to store additional objects and have a working stand.  The student drafted and initial designs were challenged to be improved to include more features not combined together.
Above: iPad Stand in use.
Timeframe: Ten hours. Given the size and the details in this project this represented a minimum time of print (where rafting for instance was at a minimum).  This was conducted with a 8mm nozzle on a regular print setting.
Size: The demensions of this print were slightly affected by the designs and not consistent throughout.  The base was 15cm in length and 7cm long.   The Minion design at the end of the stand was 6cm long and 6cm high.   The student cleverly included his name on the head of the minion and this formed the basis of the hair of the stand. 
What we would do differently: Nothing - the student created something unique that was a significant improvement on the previous designs in this series, the only significant feature that needed to be improved was the location of the hole for additional storage, depending on which item was stored the iPad itself would mean that it couldn't fit.  This location needed to be refined.
Next Challenge for student: to relocate the hole to a place on the iPad stand where it didn't have an issue with the lean of the iPad itself.

3D Printed Student Bag Hook V2.0

Challenge: Student wanted to design a personalised bag hook, that would be functional and personalised.   This design was originally created with a 'cone' shape, testing revealed that the bag would simply slide off making the design not work.   This design was created to adjust and solve this problem.
Background: Student was showing creative design instincts having previously been responsible for the jewellery box design amongst others.   The first design had failed, this was an attempt at an improvement to resolve the issue.
Level of Difficulty: Medium.   The design premise is basic, however there has already been a considerable reworking of the original design based around problem solving.  There is another area that requires considerable redesign - as viewed in the photograph above you can clearly see that the screw holes in the base of the plate are 2cm across.  This clearly would not work with anything other than extremely heavy and large bolts, which would not suit the purpose of this design.   
Timeframe: Seven hours - this design should require further refinementm the hook itself at present is 6cm from the base, the purpose could be achieved by having something half this distance. 
Size: The dimensions of the print are a depth of 5mm.   8cm wide, 12cm high.   As mentioned the hook comes out 6cm from the base.   The rectangle is 3.5cm by 3cm with a width of 2mm.   The base plate has a depth of 5mm.  Strength testing is required to see what weights of school bags could be held up and what the timeframe would be.
What we would do differently: The task needs to undergo strength test see what weight of school bag could be held and for what length of time.   The holes for the two screws to attatch to the wall need to be resized and redesigned. 
Next Steps for the Students: To considerably redesign the mounts for the wall and to possibly have a third screw hole at the bottom of the design.   The size of these needs to be refined.   There is a clear need for significant strength testing based on the size of the design, the weight of school bag that it can safely have (relative to the wall) and the length of time it will hold it for, which would be an amazing Mathematics lesson.

3D Printed Mouse House - Extended Version

Print showing the entrace to the 'Mouse House'
Background: Student to designed a container that would contain a working mouse trap.  This would protect a domestic animal or young child from setting off the trap accidentally.  This is the second version of this project, with the first featured here on this website (although this was considerably larger).
Background: This was students first individual attempt at 3D Printing by the student who was nine years old.   It was for a showcase (which has featured on a number of projects that have been featured on this site).
Level of Difficulty: Medium.   The design was significantly large (see details of the Printing Time).  The basic shape was from the Tinkercad interface wtih the addition of a hollow out section for the placement of the trap.   This design was printed with an extremely large amount of 'rafting' to allow the shape to be completed.
Timeframe: Twenty-Seven hours.  Given this fact this was a 'one off' print this was acceptable, the print itself could have been resized given the design brief, which would have leant itself to a considerably shorter print time.
Size: The dimension of this print were considerable - 15cm at the height of the roof structure.   The print was 15m long and 12cm wide.   The width of the walls was 5mm thick. 
What we would do differently: The print allowed a student to have his first experience with 3D printing and great a significant design.  The student could have personalised this design with thier name either externally or internally.   The shape/size came about as the result of the students experience with 3D Printers - while it worked it could have had considerable redesigning.
Next Steps for Students: As above - redesigned and personalised.

3D Printed Movember Cookie Cutter

This variation came through Twitter today, combining an idea from a post on this blog to include it as part of the 'Movember' (New Zealand Prostrate Cancer Awareness) idea.  Great stuff Nathan.

Expected Print Time: Depending on Nathan's set up, nozzle size and PLA Filament in use we would expect this print to run in the forty five minute timeframe.

Thoughts: This will allow a group of students potentially to be exposed to 3D Printing, the print time is extremely realistic given the task and its a fantasitc idea to link it in with a relevant fundraising cause.   

3D Printed Presentation Props Part 2

Challenge: As noted previously to enhanee a presentation for the local community and group of schools.  The displays were static and generally two dimensional, by adding 3D figures 
Background: The presentations had the typical 'science fair'/board set up and we were looking at something to enhance the presentation, by adding additional features, in a 3D sense, to improve or have a point of difference.  Due to the auidence (adults) and timeframe the props were for the most part used from a search on Tinkercad.  These were not designed by students - they were created by third parties and re-sized and printed by the students.

 Left: One group was presenting about the 'Pests' in the School area.  They identified that feral cats were one of the creatures and used a 'cat' search to locate this design, which was then increased in size for a ten hour print.
 Left: The 'Pests' group also identified Hedgehogs (which are protected in parts of Europe, but considered a pest here in New Zealand.  This was located from a general search by students on Tinkercad and then re-sized for a ten hour print.
Left: As part of a 'Machine' themed display this student located a series of machine cogs, printed them out and then hung them from the display board to form a border.  Each cog took approximately forty minutes so the tray of nine shown here was six hours altogether.

3D Printed Presentation Props

Glow Worm
Challenge: To choose suitable props to enhance a school presentation.
Background: This is another task to enhance a presentation to take place for the local community and a cluster of schools.  The classroom was developing projects based around two similar themes, gaden worms and glow worms.   As a result of conversation with the teachers of the classrooms an offer was made to enhance the presentations by producing 3D printed models that would then be mounted on the boards.   For the 'glow worm' presentation glow-in-the-dark filament was used.   Due to the timeframe available a decision was made to go with pre-produced material, that was not student created.  (this is the second time this has occurred on this blog, the first being the 'rat' print listed previously which is also linked to this presentation.
Level of Difficulty: Minimum, none.   These prints were sourced from pre-produced locations (in this case a generic search on Tinkercad) and not requiring any student created input.  The only factor that slightly complcated matters was the use of glow-in-the-dark filament for the glow worm.  This filament as a general rule is more difficult to print and requires a adjusted temperature and multiply tries to compete successfully. 
Full display, worms in green
Timeframe: Approximately 40 minutes per worm.  They varied in size and as a consequence the time for each individual piece was different.   The times was a minimum required and as a sourced prints, other than altering the size, minimum changes could be made.
Size: As above the size of the worm/glow-worm varies on a case by case basis.  The longest in the series is shown top left, 12cm.   The worms featured in the display on the right at right angles were this size but split in half due to the angle of the bend.
Collection of 'Tinkercad Worms"
What we would do differently; If time had not been a constraint then it would have been preferable for students to design and create their own individual and unique worms.  Given what students have produced in the past, this would have been more than possible.  On a positive - two furher teachers were provided with practical examples of something produced with 3D Printing, and their displays were enhanced.
Next steps for students: The obvious  is for the students to design the worms or animals from scratch.  This would be well within their capabilities and the animal shapes and design could be inspired to create their own versions that would more than suit the purpose.

3D Printed Glow in the Dark Container

Container with lid
Challenge: To produce a working container for a School display that is functional and able to store items.   Glow-in-the-dark filament was used to create a point of interest/wow factor.  Container would need to feature a working lid that worked in conjunction with the base.
Background: Group was looking for an item to feature as part of their display for a school and cluster (group of schools) showcase taking place for the parents and local community.    The students had a background in design using Tinkercad having spent most of the year working on the projects featured on this site.  Students were nine and ten years old.   Design was created using Tinkercad and Cura for Printing.
Level of Difficulty: Low.  The students design was complicated only by the filament used.  With our experience with the glow-in-the-dark-filament, instead of regular PLA the quality of the print tends to be compromised slightly, we have investigated changing the print settings but tend to get more challenged prints.   The basic Tinkercad interface was used to produce the base, the lid, the drop
Filament 'burn' shown on container
down lid on the inside and the handle.  We ran the print twice to get a better result from the filament with exactly the same design and settings (this was the first of the new roll of filament).
Timeframe: Six hours.   Print times are exactly the same regardless of the filament used.  The shape could have been slightly refined depending on the purpose of the container of what it was holding.
Size: The base design was 8cm across and 8cm high.   The width of the internal walls was 5mm.   The lid had similar dimension being 7cm across, a 1cm depth in total (including 5mm drop down lid) the handle was 3cm high.    As noted these dimensions were created by the students with the design of the container in mind rather than specific for the project.
What we would do differently: The name of the students and the group that they working as part of could have been included in the design - the lid itself while it had a drop down aspect fitted losely.  Both these things could have added considerably to the design and the project. 
Next steps for students: Research the temperature settings for Glow-in-the-dark filament and then experiment with alternative temperature to reduce the 'burn' part of the printing process shown.   As noted above the container could have been more personalised.

3D Printed Mouse Trap House

Mouse House with trap insert visible
Challenge: To produce a 'Mouse Trap House' that is a structure built to hold a mouse trap to ensure that it can still activate but isn't able to be accessed by a third part such as a pet or young child.
Background: Student was producing a 3D print for the first time as part of the a class project for a showcase that is taking place involving a group of local schools.   Class and students had been looking at mouse traps and determined that if an animal was able to access them or a child was able to access them easily then they could be dangerous.  The solution was to create an orginal design that was capable of housing the Mouse Trap itself, allowing the mechanism to fully operate but would not allow the trap to accidently set off.
Level of Difficulty: Medium.   The design was complicated by a significant internal aread that needed to be able to house the mouse trap, with enough space for the trap to be able to spring, with the trap fitting inside it.  This required the removal of considerable rafting from inside the design.
Timeframe: Ten hours of total print - the design could have benefitted from slight revision, however the internal mechanics of mouse trap and the housing goal determined a lot of the shape and size.  There could have been less infill with the design.
The Mousetrap used in conjunction
Size: The base of the design was 7cm across,   the height of the design was 6cm, the thickness of the sides throughout the design was 5mm (which is pretty much the minimum required to make this print successful).   The length of the design was 6cm.   The variations and specifics of the design were based to house and keep the mousetrap - which was a 'The Better Mousetrap By Intruder' brand of plastic, spring based mousetrap.   This mousetrap is quite sensitive and one of the issues with it is that it could easily be set off by movement.
What we would do differently: The challenge for the student was to build something that works in conjunction with a particular  brand of Mousetrap.   Testing is required to ensure that enough space has been produced/created to allow the spring and the trap to fully set and then release when the pressue plate is touched by a mouse.
Next Steps for Students: This project is going to undergo testing as described above to ensure that it is still able to function.  The idea is innovative and creative and addresses a specific problem related to the use of the mousetrap and has been student driven, created and produced - a great result.

3D Printed Dual Desk Tidy

Design shown from above
Challenge: For student to create an original design that would allow working material - pens and pencils etc. to be stored on the desk of two students with a shared design. Students creating this design were ten year old students.
Background: These projects had been attempted earlier in the school year, however these students (two were involved in the design) sat adjacent to each other and as such wanted to create something that they would be able to each use.  They used Tinkercad and built the designs from scratch, to personalise the design they etched or sank their names into the side of the hexagon shape that made up the storage tower.
Above: Lettering shown on storage 
Level of Difficulty: Low-Medium.   The students were personalising the design by the addition of thier names, they also used an unusual shape with the design which the class had not utilized before.  The lettering was sunk lightly into the design, so the angle of the design meant some of the letters in the names were clearly visible and others were slightly more difficult to see.   The students identified this as rafting at one point and 'knock it through' however this the case and it left a letter of one name looking different from the rest.  Given the basic shape if they had attempted all the letters to be rafting then the design would have been considerably more challenging.
Timeframe: Eight hours on a 8mm nozzle and regular print settings.  There was not a lot of material that could have conceivably been removed from the print or added to it.
Size: 1cm base, 13 cm wide, 7cm high.  The barrel portions of the design were 9cm from the base.
What we would do differently: Minimal - the only issue that developed was consistency with the lettering as it inconsistent, although this was related to the shape of the object which the students were using as a feature of the design.
Next Step for the Students: More challenging projects as this was completed to the students satisfaction and not more material could be added or the design modified.

3D Print Student Bag Hook

Above: Overview of the design
Challenge: Student wanted to create an original design - a hook, complete with their name and personalised and designed to be mounted on a wall and used to hold thier bag.  The student responsible for this plan/design was a nine year old.
Background: Student was following the classroom process of selecting an original project, which was created from scratch that would have a purpose.
Level of Difficulty: Low.   The design had three key features as shown in the photograph.   Firstly a hole, which was intended to be used as the mounting hook.  Secondly the name of the individual who created it and finally the 'hook' part of the design which was created to hold the students school bag.
Note: 'Hook' needing redesign
Timeframe: Four Hours.  The base of the bag hook was designed featuring a 1cm base, conceivably this could have been 5mm (subject to strength testing, and the design for the hook - see below). 
Size: 7cm wide, 10cm high and a depth of 1cm.  The lettering was raised 5mm from the base and the point of the hook itself was raised 5cm from teh base.
What we would do differently: The design is essentially floored, but will turn into a learning project for the student.   The idea is solid, however the project is not workable.  The mounting design should have been placed in the opposite top left and right corners, rather that the middle.   The 'hook' which is cone shape at present needs to be completely redesigned to suit the purpose of the print.
Next Step for the Students: 'Hook' needs to be completely redesigned to meet the brief.  The hole to mount the design to the wall needs to be replaced by dual screw holes as mentioned.  The intention is to allow the student to test the design with a bag, which would then allow a re-design, and allow for testing on the weight of a bag to be successfully held by the design.   Could potentially be used to individualise the outside of the classroom.

3D Printed Delux Business Project Container

Container with lid in place
Challenge: Students are creating a contained suitable for holding liquid.   Container needs to be accessed by a lid which is able to work in conjunction with the base. 
Background: Y4 Students were producing a 3D print for a student based business, which was be presented to the local community for an evening event.  Students in this classroom had produced smaller versions of this previously document on this blog.  Students were using Tinkercad for the first time, with the basic interface was utilized.
Box shown with lid.
Level of Difficulty: Low-medium.  Nearly every previous print in the sequence had issues with the lid matching the base.  In this case the students designed a lid that fitted perfectly. 
Timeframe: Ten hours were required to print the base and the lid.  The size of the container had been designed by the students and perhaps could have had reduced dimensions (see below).
Size: The base of the container  had a length of 8cm, a width of 8cm and a height of 10cm.   The width of the size was 5mm.  The size of the lid reflected these dimensions with a total width of 1cm split into the lid and the drop down aspect of the lid (as shown top right).
What we would do differently: Given the aspects of the design and it originating from a student creating something for the first time, it was an extremely successful print.  The student was using a printer for the first time, the design features while basic meant that the student was thrilled with the results.
Next Step for the students: A handle could have been added to the print to allow it to be easily removed, which would have been a basic step to take, the student could have also experimented with design features.

3D Printed Advanced Box

Box Complete with lid in place
Challenge: To further develop childrens creation skills by focussing on producing a more advanced project with two parts reliant on each other and dependent on a successful print.
Background: Y6 student (11 years old) is creating the first next level print that is more advanced and detailed than previous efforts.   Student was using Tinkercad with assistance of other students to produce details on the lid such as the handle.
Level of Difficulty: Medium - the lid needed to work in unison with the base, and the student was challenged to create multiple lids that could be interchanged depending on the use of the object.  Once again all of the major elements that were the design features for this object were provided by the main Tinkercad Interface, which the student created independently.
Timeframe: The base of the box was significant taking ten hours, the lid required eight hours.   There could have been adjustments made to the lid shown above, to reduce the time (decrease in handle size).
Size: The base of the box was 15cm wide, 7cm high and 15cm long.  It had a width of 5mm.   The first draft of the lid (as shown above) had a lid size of 15cm/15cm and a depth of 5mm.   The handle sat 4cm above the base of the lid.   The lettering was raised on slightly on the lid, 2mm. 
What we would do differently: There were no issues with the print itself but the students didn't initially grasp the concept of the 'drop down' lid and what potentially it meant for securing the lid. The student also made the design not to put a divider into the inside of the box, so as it stands at present it does not have inbuilt dividers that would define its use. 
Next Step for Students: Obviously the drop down lid, potentially more detail on the lid and internal division brackets that could define the use of the box, such as featured in the Jewellery Box design, iPod Carry Case and Edison Robot Storage Box.

3D Printed Basic Box

Above: Lid and base plate design
Challenge: This was a further development from the student led business model that was created by a class of Y4/5 students (making them nine and ten years old).  The students were attempting to personally create a brand and product which could be marketd to other students.
Background: Students concerned were looking at creating something striking that would impress their potential market, hence the size of the box, which was significantly greater than corresponding designs.  Students were creating products for the first time, using the basic designs possible from the Tinkercad Interface, without the assistance of the teacher or other students.
Level of Difficulty: Low - this design was created in a short space of time, using some of the basic settings available from the Tinkercad Interface, by students not familiar with the program.
Timeframe: The lid and base were a combined ten hour print, the design was based around size so the details were specific to the design. 
Size: The base plate was 7cm wide, 7cm high and had a depth of 9cm.  The width of the sides was 5mm.   The lid had similar dimensions with the main part of it being 1cm.
What we would do Differently: This was a starting point for the students concerned - hence the complexity of the design was reflected by its background.  The students could have looked at ingraving or dropping the names of their business into the base of the box, this has been achieved to good results in recent prints.  We've had students previously add additions to designs such as lids or handles and students could have considered these (they are available from the main Tinkercad interfaceand intracate designs are able to be selected easily).     
Next Step for students: As descibed above.  Given time contraints with the project it may remain as it is.

3D Printed Spoon and Cup/Mortat and Pestel

Challenge: Student is involved in a upcoming showcase of students work.  The student is creating a series of products based around fragrance and hand cream.   The design was to create a basic mortar and pestle set, which is described by the student as a 'spoon and cup'.  The set needs to be big enough for the student to use it to manufacture/mix the hand cream.
Background: The student is working with learning support with a teacher aide to produce the product.  The teacher aide has not used the 3D Printer previously to produce a product, the student requires learning assistance from other students to complete set tasks.  This was both (the teacher and students) first 3D Printed project.  The student was a Y5 (nine year old) who typically works at curriculum level 1 (Y1 - five years old).
Level of Difficulty: Low.  The student was experimenting with size, design and completing the task.  The basic Tinkecad interface was used to create the required shapes, which were then extended by the student by dragging them.  A cup and spoon were used as a model to ensure that the size was relatively correct.   In the case of the student the oversized spoon is an advantage.
Timeframe: Both objects in the matching set were completed in ten hours - they could have been resized slightly given the brief, and adjustments made, but given the scale and the first print ever nature of the project this was
Size: Both prints were combined on a single run.  The 'spoon' was 16cm long, 2cm high and 3cm wide.  Conceivable it could have been thinner or smaller however given the student concerned the bigger item was more desirable.
What we would do differently: Our class typically personalises items such as this.   Clearly it would have been easy to insert the students name into the spoon and cup, or both.     This didn't happen as the skill set wasn't there yet but once this print is discussed and the student spoken with (and the staff member) then other students will assist in getting it completed.
Next Steps for Students: We are anticipating other students come on board to assist with the more detailed aspects of design.  There is the obvious step of personalising the cup and spoon with either the name of the student or the business by dropping it into the cup, and then to remove rafting, as has been done on previous prints/projects.

3D Printed Hair Tie Stand

Above: Design shown from above
Challenge: Student wanted to create a hair tie stand to store hair ties that were all over the place. The design needed to be flexible and personalised.
Background: Coming back from the school holidays a Y5 student approached me and stated that they had an original design which they had thought of during the break, to solve a practical problem. This was the students first original design meeting the expected classroom brief.
Level of Difficulty: Low - the design was straightforward and featured basic designs from the main Tinkercad interface that were then adjusted to complete the design. The original design was not personalised, so the name was added last to reflect the student and increase the difficulty
slightly. Additional features could have been added to the base (such as multiple words or extra shapes).
Timeframe: This design was an six hour version, with an 8mm nozzle as stated. Obviously the size of the cone was variable and could be redesigned depending on the choices of the students and the stand wouuld still function.
Size: 11cm long, 9cm wide, a width of the base plate of 5mm and a height of the cone section of the design of 9cm from the base plate.
What we would do differently: Very little, the design was original, which fits the general brief. It addressed a problem or an issue that was relevant to a student and was successfully solved by a print.
Next steps for the students: The student was able to idependenlty complete the process without any teacher interaction. With the next step would be something more complicated, another original design that would potentially include interlocking pieces or working/moving parts.

3D Printed Basic Tap Design

Tap with block insert pictured right
Challenge: To create from scratch a tap (faucet for our American friends) that would be viable and working suitable for use with a worm farm.  Students involved were Y2-Y4.
Background: Junior School students from another classroom had been creating a realistic sized model of a worm farm for a showcase (parents eventing).   They had mocked up a model but the teacher as looking for something extra to complete the display.   Our class released two students to work with the junior school students.  For both sets of students this was their first original Tinkercad and 3D Printing designs.
Tap with square insert to act as block
Level of Difficulty: Medium to High.  The inital design process involved a challenge to the students to produce a working tap.  With little design experience they attempted to design a working tap - however they were redirected to keep it simple, by producing a tube shape with block that could be inserted into it to act as a block (as shown above).  Once this was successfully printed the students would then start to examine the process of engineering related to a tap and more advanced.  Ideally this would lead to a repeat of the process where the students would look at a more complicated solution.  One of the basic designs 'block' piece did not seal the pipe successfully the student had not considered the implications of producinga square block instead of a round one.   The
Timefame: Initial prints in the series (not featured) were 45 minutes.  This allowed the students to refine their design (as pictured) which put the design (including the block) at two and half hours.
Size: 7cm in length, 2cm high (the deisgn was of course hollow which included significant internal rafting which then needed to be removed using pliers). 
What we would do differently: This print is a work in progress.   The intended progress is to give the students design experience and advance them forward in the process.  Although the 'tap' concept with initially daunting the students concerned have made an excellent start and are already looking to refine and improve their design, hopefully showing a considerable improvement and refinement as they progress with the ideas.

3D Printed Animal Bait Station - Personalised

Final Print with name aspect visible.
Challenge: Having completed the design, testing and refining of a student created 3D Printed Bait Station, the students were considering ways in which to personalise the creation.
Background: This design and process has been described indepth before on previous posts on this blog, the difference was an addition was made, as shown in photographs, that the name of the person (in this case from the Taranaki Regional Council, the pest control officer was added to the base of the print) was added.  This was for the purpose of identifying the bait station, and obviously this could be modified to introduce the name of a company or organisation or even number the bait stations in sequence for recording purposes.  It was also considered that the students could produce something similar for fundraising purposes, with the name of a company, or individual added to the print run.
Level of Difficulty: Low - the print has not changed since the development of the extended feet, the only addition to this version was the naming which was completed with basic lettering that was taken from the main interface of Tinkercad, this took the student within three minutes to complete.
Above: Hedgehog in action at night
Timeframe: Ten hours (original print design) adding the lettering did not affect this in a significant way.
Size: The lettering likewise did not alter the dimensions of the design significantly, evidence from the night vision camera has identified that the Hedgehogs are unable to dislodge the bait stations from the ground by tipping them over, as once the station is buried in the ground with the
legs featured above enough resistance is created to prevent the toppling of the bait station.  We have photographs of hedgehogs attempting to do just this to allow them better access at the bait.
What we would do differently: The students will be moving on to other projects as this one has been mastered, the only exception would be the production of individual bait stations in some form of economic process (such as a student market day) or gifts to the appropriate organisation associated with the school.

3D Printed Student Business Projects - Part Two

Above: Conditioner holder with lid.
Challenge: For students to produce a container/packaging for a classroom created business project.  The container needed to be able to hold liquid or cosmetic products.
Background: This is the final draft print of the classroom set designed described previously.  In these two examples students were looking to create containers that would hold samples of conditioner and lip balm.  (the cosmetics were to be produced seperately in the classroom and this is the sample box).
The students concerned were a Y4/5 classroom - nine and ten year old students.  This was their first 3D Print designs, which were created by students using Tinkercad, for the first time. Students were producing a prototype with a base and a lid, and experimenting with the lid being able
Above: Lip Balm storage container
to be dropped into the base to seal the container.
Level of Difficulty: Medium - the issue consistently with this set of designs and prints was the lid.  The two lids in the case of both of these prints were no exception.  In both cases students had designed the lids without due consideration for a reduced inner lid which would allow the lid to drop into the base.  In the case of both of these designs students are going to re-design the lid and drop down the size of the lid insert so the base will work with the lid clearly in place allowing the concept to be successfully completed.
Timeframe: The heart shaped box was two and a quarter hours, the taller box featured above was five hours (both print time included the lids both printed at the same time.   This was on the normal print setting, with additional rafting to support the inserts.
Size: Right - the heart shaped box has a width of 6cm across a height of 2cm, the lid being slightly smaller.  The larger container had similar dimensions with the exception of the height which was 8cm. The width of both prints were 5mm and was above right from a size perspective.
What would we do differently: The boxes/containers need to have the lid reprinted because with nearly all other objects in this set the students underestimated the need to reduce the inserts allowing the lid to drop into place.  The students as noted are going to redesign the lids and re-print them reducing the inserts, the bases are remaining, so overall the prototype succeeded in meeting the breif.

3D Printed Student Lip Balm Holders

Above: Rounded Lip Balm Design.
Challenge: For students to produce an original working container that was suitable for holding liquid or lip balm.  Created by Y4/5 students in New Zealand who were nine and ten years old.
Background: Next term our cluster of four schools have a showcase where the students have worked this term on a significant project.  The class next door are making authentic products to showcase and as a result the students used Tinkercad to create a container for their product.
Above: Outside 'rafting' clearly visible
Level of Difficulty: Medium - both these designs needed significant adjustments which the students will repeat.   Both included text and design that were printed on the outside of the 3D Print, which contrasted with designs that have the lettering inserted into the base of the design.  These desings in addition were round in shape instead of being square.  When 'rafting' was removed the lettering itself would be removed from the shape, negating its effect.
Timeframe: For producing something such as this with an 8mm nozzle (various designs are shown all with slightly different timeframe) you are looking at a six to eight hour print time.  The prints are essentially variations of the same theme which is why I have group them all together in a similar post.  As a consequence these prints for various reason will be reprinted shortly.
Note lettering starting to be missing detail
Size: As above and shown in photograph.  The lids are in the 4cm to 6cm range, the base have a range from 6cm-10cm with a height in the range of 10cm to 20cm.
What we would do differently: The lettering will be redesigned to reflect the size of the prints - and an attempt to shift the lettering from featuring on the outside of the print to the inside.   This is illustrated in the print to the left which the lettering is starting to show signs of missing parts of the font.  We used an 8mm nozzle for this print, on reflection we could have shifted to a 4mm nozzle and this would have allowed more detail into the print - however the problem would have been that this would have doubled the print time and there are a number of prints in this run for the class of students that need to be completed, and this afterall is a prototype to test the production skills of the student and allow them a first attempt at 3D Printing.

3D Printed Student Lip Balm Holder

Heart Shaped Box viewd from above.
Challenge: For student to produce a functional lip balm holder, with a working lid.  The students who created this project were nine years old (working at Y4/5 level in New Zealand)
Background: This is the second featured print from the series previously described here.  The idea was for the student to produce a product that could be marketed to the general public and this is a test pot, featuring the lip balm with the logo of the business allowing people to sample the produce.
Lid wtih rafting present.
Level of Difficulty: Medium - although the print is not significant in size the design featured a working lid that was required to be printed seperately and work together in conjunction with the base.  This required a drop down lid with an insert/lip that would allow it to sit ontop of the base.  The print was successfully completed with the base the first time.  The lid when the 'rafting' was removed (by the teacher with pliers) an adjustment needed to be made with the insert as it required a further layer of removal, this was completed by the parent of the student who designed it, in his workshop at home.  (Had this not been possible we would have simply reprinted the lid with an decreased 'lip' insert which would have been in the one and a half hour to two hour timeframe).
Timeframe: Eight hours - 8mm nozzle size, with standard PLA.   The process was completed by a Tinkercad design followed by a conversion to Cura (the new updated version) and then printed.
Completed print with lid
Size: Both designs were printed 1cm high, a height of 9cm and 6cm across.  The idea was that they would sit in the hand of the person holding them.
What we would do differently: The students have produced something that has solved the brief in a really positive experience for the students.  They were able to design and create an original Tinkercad project which then translated extremely well into a 3D Print.  It was the students first experience with 3D Printing and has allowed an original eye catching prop to be completed for their presentation.

3D Printed Student Business Project Containers

Container and lid before rafting removed
Challenge: For student to create and print a unique personalised container that was suitable for the holding or storage of liquid (conditioner).
Background:   All of our students have a significant showcase coming up.  As part of this the students in the classroom next door are producing a range of products that are unique which they create which they would like to brand.  3D Printing allows them to engineer and design their own products (using Tinkercad) and then create them.  The students in this case are nine and ten year old students.
Two lids, reprint on the right
Level of Difficulty: Medium.  The students were designing for the first time and were able to have students assist the process who had 3D Printing experience.   There had to be a re-print of the lid as, as the drop down aspect of the first print did not work.  It did fit however the fit was extremely tight and wouldn't have been easily removed.  The student was made aware of this issue and created a second lid, which was a seperate print, the internal aspect of which fitted much better for the purpose of the print.  
Timefame: Ten hours for both the base and the lid in this case.  The second reprint of the lid, when it was just produced on its own took two hours.
Size: Ten centimetres for the height of the container, 6cm across.
What we would do differently: Very little.  The students concerned meet the brief that they had created and were excited with the results.   It was a successful print, allowed for a degree of individualism and created a unique print for the student.  The student had not had significant previous experience using Tinkercad but was able to confidently produce the print.  (The teacher had to remove the rafting using pliers on this occassion).
