Background: While the student involved in the creation of this project is nine years old and has only been working with the 3D Printers in a classroom context for a relatively short time frame this student has demonstrated creative flair and understanding of what is required. As such when discussing this brief with her we were looking to challenge her specifically to include storage in her design, which she did by considerably hollowing out the base of the design, designing a separate draw to be inserted into the design, complete with a handle. The student worked on a number of concept models with this project before she was happy to run the design.

Level of Difficulty: High. This is about as challenging as it gets for a nine year old with regards to 3D Printing. The storage base shown in the photography needs to work in conjunction with a drawer that has to be a perfect fit to allow storage to be used. The student has to ensure the draw takes into account the perfect size to work in conjunction with the base. The student has not completed this design to date, as she has had to revise the design, shape and design of the drawer. In the original shown above the entire base of the draw was hollowed out, on revision three quarters would have been more suitable. In addition to the above challenges, the last aspect of the design would be to mount a horse on the base of the design immediately above the base.
Time frame: There was essentially four prints working in conjunction here. The first was the base, the draw insert was then developed on the basis of the size of the base. The third was the blue PLA/ design featuring the name and the horseshoe. The fourth part of the design was the animal (which in this case is going to be a horse) which is going to be the featured animal/main design for the storage. The times for the various component pieces are twelve hours for the base, six hours for the draw, one hour for the lettering and the horseshoe and it would anticipate five to six hours with a total time in the range of twenty five hours.
Size: The base of the design measured 100mm across, was 20mm high, and was 130mm long. The block at the back was 110mm high, 10mm wide and deep and 100mm across. The draw that was designed to fit inside was 120mm long and 90mm wide. It was between 10mm-20mm thick in places. While the horse has yet to be designed and printed, it will fit within the dimensions of the base of the storage item.
What we would do differently: The design has proven to be challenging for the student. As an entire project, to get everything right (which the student has yet to do) there are some notable parts that need to work in conjunction. This has proven to be a design that has taken several days for the student to work on (please note the student is creating this design in their own time in the majority of the cases, they are not creating and designing as such in class time). This print when finished will feature inter-connected parts, a variety of prints, personalised with the students name and storage that is not apparent when the design is first viewed.
Next steps for student: The student needs to redesign the draw so that it fits in conjunction with the base. It has been discussed with the student for the introduction of a hidden storage component or a second draw in the base of the design. This print will be updated when it is in its final state.
