3D Printed Desk Organiser

Above: Original design shown to scale
Challenge: For student to create an original design that had a specific and working purpose.
Background: Student was given the opportunity to create a project of their choice, and designed and created a pencil and pen holder that would be functional and for use in the classroom to sit on the students desk.
Level of Difficulty: Medium.   The task involved a number of inlays to hollow out the inside.
Size: 9cm high, 6cm wide and 6cm deep.  The inserts went within a short distance of the base to allow a variety of stationery to be held.  
Above: View showing holder clearly
Timeframe: Eight hour print - a high grade of PLA was used as this was the current roll.  
Issues: None, from design to print it worked perfectly, there was a minor issue with the base, although this was not related to the design and was solved by the use of superglue in one corner.
Process: As per the 'norm' on this site at present the process was design in Tinkercad, the .STL then switched to Cura for printing on the Ulitmaker 2+.
What we would do differently: Given the success of the print and the task for the student little would be done differently.  It allowed the student to produce a practical object that had use in the classroom and was successful for the purpose which it was designed and was printed for.  This was the students first design/print.

3D Printed Parent Designed Keyring

Above: Parent designed keyring
Challenge: Looking for opportunities to improve the partnership between parents and students we held an opportunity for parents to come into school and use the 3D Printers independent of the students.
Background: This was an opportunity for an adults first design, from scratch, without prior knowledge and use of Tinkercad or an iMac.  The session was designed as part of an introduction for parents and the design time allocated was ten minutes.
Level of Difficulty: Low - (however this needs to be put into the context of who was designing the project.)
Size: One of the smallest prints that we've ever completed.  5mm depp, 2cm wide/high and 5cm in length.
Timeframe: 45 minutes on a regular print setting.
Issues: The first print (pictured above) had some issues with the hole in the top right hand corner, this caused a second print run to occur, when the problem resolved itself.
Process: It was initially hoped that the parents would be able to complete the project independently, however this was not going to occur in the timeframe so two students came and completed the process.
What we would do differently: This project is one that the students felt confident in assisting with, and given the straightforward to ensure that the parents were able to complete the task successfully.

3D Printed Gift Ideas (Beginner)

Above: Desk stand gift for parent.
Challenge: Student wanted to produce original gift to give to two members of her family.
Background: These designs were created by the student in her first attemps at 3D Printing, without input from others.  The student had been part of the class producing 'Christmas' themed decorations last year however this was the first opportunity for her to print individualised projects.
Level of Difficulty: Low - these designs were created with basic default settings from Tinkercad, and required a basic design.
Above: 'Alyssa' star gift with rafting clearly visible on gem (top).
Size: The 'rural fire' desk stand was a block design that had a depth of 2cm, a length of 10cm and a height of 8cm.   The 'Alyssa' star design was 15cm across, with a depth of 1cm.
Timeframe: Combined eight hours for both projects.  Both were printed as a 'fast print'.
Issues: 'Alyssa' star design lifted on the base and had to be superglued, this was an issue related to the filament, not the design.  Both designs were basic but produced the required result.
Process: Tinkercad with the design all created from the basic interface.  Converted to Cura for printing on the Ultimaker 2+.  What we would do differently: This task has been detailed before, or variations of it.  It has proven suitable as an introductory print that could be easily designed, printed successfully by the student who was extremely pleased with the results.

3D Printed Gift Box lid redesign

The first lid (left) and the refined improved version (right)
Challenge: Following on from the previous sequential print the student was unhappy with the quality of the lid.  He was insistent on redesigning the lid to improve the finish of the print.
Background: As noted in the previous details two aspects of the lid of the Mothers Day Gift Box had not proved successful.   The rose had been printed as part of the lid and then manually removed - which left residual filament on the lid.   The handle for the box detatched when the print was lifted, the lid was increased in size and sunk deeper into the lid to provide more strength and stability.
Level of difficulty: Low the student had got significantly close with the first print, and was given the option of using this lid in the final version.  He wanted to improve its design and was
therefore making adjustments to the print instead of designing a new lid.
Size: 10cm by 10cm to a depth of 5mm.
Timeframe: Seven hours.
Issues: Non - the two probelm areas were successfully addressed.
Process: Tinkercad/Cura, refining of already created work.'
What we would do differently: The student (Y5/9 YO) was driving the design and the process.  He was the one who wanted to reprint and we were happy to allow him to do so, on the basis that he had created an original idea - this should allow a student to move onto greater things in the future and should also be put in the context of the student creating his first challenging print and doing so in his own time to completed the project.

3D Printed Gift Box

Above: Completed in two stages - gift box with lid
Challenge: Student given free range to create an original design piece from scratch.
Background: This student had produced a name plate, was then looking for an additional challenge to really stretch himself.  He came upon the idea of producing a gift box for either Mothers Day (which is this weekend) or for his mothers birthday (if the timeframe would prevent it from being ready).  The student is a nine year old student who was experiencing an opportunity to use the 3D Printer for the first time.
Level of Difficulty: High - this was a challenging print in multiple stages involving significant planning.
Size: The print was constructed in two significant pieces.  The box itself had a 10cm base and width and depth of 10cm.  The lid was 9.5cm by 9.5cm with a depth of 5mm.  This allowed it to fit into the box itself.
Above: Box with interior visible
Timeframe: Box - ten hours.   The lid was initially eight hours and then seven hours with the reprint.
Issues: The lid initially had two aspects to it, the handle pictured above and a rose next to it.  The rose did not print successfully and was removed (as seen by the filament on the lid above).  The handle was removed as a result of printing and detatched the first time it was picked up.  The box itself held a number of objects that were built into the sides of it 'Mum' and a heart on the other three sides.  The box contained considerable rafting to allow it to be layered which had to be removed.  The finish was not perfect on the base when the rafting was removed, but this required some basic sanding and the use of a craft knife.  As a result a repeat print was made of the lid, with the second version having a removal of the rose.
Above: Lid seperate with handle visible
Process: Initial design was created in Tinkercad.  The design was then passed between three students, the one with the original design and then two who contributed tweaks and details to the completed project.
What we would do differently: Not a lot this is an example of a student really pushing himself with his 3D design in creating an intricate project that had parts that related to each other.  The student refined his idea repeatedly to include significant detail and produce an outstanding 3D Print.

3D Printed iPad Stand - Delux

Above: iPad stand Mark Two
Challenge: To improve the design of the student created iPad stand.
Background: This was a follow up print to one previously designed by the student.  The student had created it independently but as a result of feedback was asked to personalise the stand and also this about providing extra support for the stand by the addition of a bracket at the back.
Above: Brace at back clearly visible
Level of Difficulty: Medium - the original print was a success but the challenge was to add value or additional features to a print that had already been successful.
Size: As previously stated, 80mmx 70mmx 60mm.
Timeframe: Eight hours with the addition of the brace and personalisation of the name, a two hour increase on the original.
Issues: the rafting provided by Cura 2 software was difficult to remove perfectly from the base.
Process: All additional changes to design were carried out by using Tinkercad and then imported again into Cura 2.
What we would do differently: Nothing.  This is a considerable improvement on the original design (which also worked fine) as a display piece and a conversation piece about 3D Printing this is an excellent example of something positive and there is clear progression for the student from his first original design (name plate) to create something with an expressed purpose.

Beginners Guide to 3D Printing

Above: Students 'heart' design
Challenge: Starter for the students to use the 3D Printer in a creative way.  Students were shown Tinkercad and encouraged to come up with a design of thier own choosing independently.
Background: It was the first time the student had used the 3D Printer as the New Zealand school year runs February to December, by this stage (May) some students had not taken an opportunity to use the 3D Printers so they were encouraged to do so. (the machines had been serviced and were previously not available).
Level of Difficulty: Low - student had not previously had any experience with Tinkercad or 3D Printing and this was produced by the student in under five minutes.
Issues: None - student was extremely pleased with the process and the opportunity to produce a novelty item in a short time.
Size: As shown in the photograph - three cm in length.
Timeframe: Thirty minutes.
Process: Tinkercad default used, with the new interface there are a number of objects that are able to be produced instantly, the heart being one of them.  With this produced the only other detail was the hole that was put into the centre (so it could be used as a necklace).  
What would be done differently: This was a positive experience an a relatively straightforward print with an extremely short print time.  Using this format as an introductory lesson or creation process it would be possible to produce an entire classroom worth of design in a short period of time and be able to print on a single printer during a short two or three day period.  The other consideration is due to the print time the students saw the machine operating from start to finish in the classroom.
