The initial design, in red, was for a student desk organiser which consisted of a named block, sunk into the back of the design and two hexagonal cyclinders which were the storage components. The original design had a twelve hour print time, and was student created.
In the revised version, which was labelled the 'ultimate' desk organsier, a student took this initial student design and added additional features to the outside of the design to further personalise it. (emoji, a donut, face and a side bar to hold in place a protractor). As a result of these further changes the print time was increased to a tweny hour print.
This revised version, shown left, focussed on reducing the width of the cyclinders where the stationary was stored. In the original version these were 25mm thick.
This version reduced the width of the cyclinders to 5mm. It also removed the emoji from the side. The consequence of this was the revised printing time which is now reduced to twelve hours.
The design has also included a bar, which can be seen in the right had side of the design to allow a protractor or a small ruler to be held.

|Above: Emoji design, yes it is.|
Background: Most of the prints on this site have an extended print time due to the size, purpose and nature of them. Occasionally the students want to demonstrate something the opposite of this, a short term print that can produce something quirky, or humours. One example that students had come to me with was the emoji shown in the photograph. The students were able to show that it would have a purpose, as a label and were able to personalize the design, and argue that they could use it as an exemplar, which would allow a quick print (in the twenty minute range for each emoji). Its a bit of 'fun' if nothing else and was given consideration before the decision to print was made. Apparently a student would use this to mark their bag or their possessions.
Level of Difficulty: Low - this is a generic design, which has been re sized for purpose and has the addition of the students name on the top, as a consequence the student who designed this was able to achieve all these things in an extremely short space of time. A small design note - the rafting on the back of the design was deliberately not removed as it allowed the eyeballs to hold in place.
Time frame: twenty minutes was enough to complete the print. They are relatively small (see notes on dimensions). We printed a group of six of these designs (each a copy with a variation of the students name) on a single print run which had a combined print time of four hours.
Size: 60mm wide, a height of 60mm and 5mm thick. The purpose of this design was to produce something that was recognizable, and could be massed produced quickly so while it could be re-sized it would somewhat defeat the intended purpose.
What we would do differently: The students wanted something for a specific purpose and could have experienced with something slightly more appropriate, however students wanted something humorous, recognizable and small and like all the best prints they completed the process.
Next steps for students: Something that was original and not a stock copy.

|Design shown from above featuring name plate|
Background: Student is able to produce a range of prints and designs and has been increasingly complex and innovative. In this example he had a desire to create a stand for his iPhone so that he could locate it easily have it promently displayed in his room.
Level of Difficulty: Low-Medium. The design itself is realatively straight forward. He took an available template (the drone template) and decided to convert it to personalise it for his use. He included a name, sunken into the top of the base, added additional backing plate and sunk a design to catch the iPhone.
|Design to hold the iPhone clearly shown by the depression|
Size: The front of the design measures 160mm across and is 180mm long. The base plate is 100mm by 100mm. The block that supports the iPhone and has the name of the student on top is 65mm high, 25mm thick and 10mm long. The depression to base the iPad is 85mm by 35mm and 10mm deep. Relative to the size of the phone these dimensions would be the minimum that would be required for this particular print to be successful.
What we would do differently: The issue that needs to be addressed is the legs. This design needs to potentially be lifted up off the ground, from a display perspective and the student has twice attempted to use legs that have been too thin and removed either partially or fully when the rafting has been taken off. The student is currently designing additional legs and a base for this design to compliment its creation.
Next Step for students: As above. The design itself was created by a ten year old student so some conferencing has resulted in more discussion about its shape and production. The student could have printed parts with seperate PLA filament and then assembled with superglue or other connectors to produce a layered affect with the colours.

The students have been experimenting with different designs and shapes backed onto the bookends.
In these draft designs students were primarily determing the size and potential design of the bookends.
Some students were using third party created material (as shown in the photographs) to enhance thier design.
There were variations in the design of the lettering for the names.
These designs will expanded on in further posts including a detailed discussion of the projects and following through the production process.
Estimated print times for this will be six hours.
Students have used a variety of additions to the print.

|Design from the front|
Background: Once they've completed the basic designs in the classroom the students have been challenged to create original and unique projects that have a meaningful application and use. This student in question was looking to design something original for various kitchen items. Student (who is ten years old) is having their second year of classroom opportunity with the 3D Printers in the classroom.
Level of Difficulty: Medium - aspects of this print could have been modified, particularly with its purpose (see below) and there were aspects of this print that could have been altered so that it worked more successfully (particularly the base).
Time frame: Ten hours - aspects of the print could have been changed, however overall the design met the brief, dependant on the size of items that were to be stored in it. This is an 8mm nozzle, on regular settings with a 20% infill (which are all the standard default settings).
Size: The dimensions of the front of the design is 90mm across by 80mm deep. The back of the design is 100mm across and a further 150mm high. The width of the design is 5mm except for the back, which creates a base by being 10mm thick.
|Design shown in profile|
change to be considered is the purpose of a container like this - while the intended purpose was for a kitchen utility holder, one thought was to have perhaps a classroom token box or a classroom container that would hold universal items (such as markers etc). Depending on that purpose then a way to mount the container on the wall etc. should have been considered. Furthermore as shown in the illustration the bottom part of the badge design where the angle touches the base is slightly below the base of the design. This is why the student hasn't removed all of the filament as it would cause the design to be slightly unbalanced.
Next step for student: To redesign the base to ensure that it wasn't sticking below the floor of the design. The lettering itself could have been designed differently and made bigger to ensure that it was more detailed with the printing.
|Above: Design shown in profile|
Background: Student has shown some creation and invention with various projects related to 3D Printing in the classroom. Student is designing a series of prints and creation and conferencing with the teacher with regards to their originality and purpose. This design, while it would appear complicated comes primarly from the main Tinkercad Interface, which has a series of basic designs that students can take and reshape, redesign and ensure that they meet the criteria for the purpose set above in the challenge.
Level of Difficulty: Low - while the design is exactly what the student had in mind (see below) the essential issue here was the redesigning of the shape created by Tinkercad and ensuring that it was able to meet the purpose. In this case the student needed to redesign the shape to meet the purpose of holding pencils and general items that the student wanted to store in it. The size, relative to the design, was perfect for the design.
|Above: Original design as shown as an .STL download file|
Size: The width of this desing was 100mm. The height of the design was 100mm. The width of the design was 25mm at the top. Conceivable the width of the design could have been reduced to reduce the length of printing time.
What we would do differently: The student obviously missed an opportunity to personalise the container with their name or the purpose of the container (however the student was adamant that they wanted this container to be multi-purpose and not restricted to one purpose as it would have been if it was created with a label).
Next steps for students: To show other students (and teachers) how to produce material/projects of a similar nature. This student has mastered this type of project and needs to extend herself in other ways.

|Above: from side showing emoji|
Background: Inspired by other students in the classroom the student designed a container for all of her stationary. This was the second recent print from the student who had recently designed a significant print to hold her iPad, as linked here. For this design she was inspired by a previous student design in the classroom, linked here. The student used this as a the base, and then added a series of additional features to the design - including a subtle face on one side, a donut at the front for effect, a side bar to hold the protractor of the student and a emoji, yes that is a 'poo' emoji on the front to one side.
Level of Diffculty: High. This print featured a number of intricate details and features that were added to a basic design. All of these needed to add and work to the design and did so.
Timeframe: Twenty hours - this was a significant print in both size, design and timeframe. Some of the features could have been reduced or decreased and given the dimensions a consideration was given to reducing the infill for the back of the design.
|Above: Design shown from above clearly showing the naming|
|Protractor holder and 'donut' design visible|
Next step for students: This student could have designed the project from start, instead of using another design as a basis for design. She could have reduced the width of stationary holders and reduced the level of infill.
