3D Printed iPad Stand and Draw

Above: Design showing the personalisation of the iPad stand
Challenge: Student wanted to create an original print, a combination of an iPad stand for use in the classroom, personalised for the student who created it, to include a built in draw for storage.
Background: This student inspired by other designs in the classroom has demonstrated excellent design and creation using Tinkercad and 3D Printing.   In this design the student wanted an advanced iPad stand created to allow her to have her iPad stand.    The personalised part of the design was to have her name featuring prominently on the top, and placed an emojii on the rear of the stand.   The dimensions of this were created, measured and designed independently by the student, to have
a regular iPad Mini sit on the stand.   The design included a hollowed out part of the base.  When the initial print was completed a second part of the design was to create the draw which could be inserted into the base.  The student delibrately choose a different coloured PLA for the print for the draw.   The student again spent considerable time ensuring that the dimensions of the draw were correct so that it could work in conjunction with the base.
The student concerned in this projecy is a Y5 student who is ten years old.  She has had two years experience with 3D Printing.

Level of Difficulty - High.  The student is designing this project from scratch and had to take a number of factors into consideration - the size of the project relative to the goal, and the inclusion of a drawer to work in conjunction with the base.   The stand was produced with a hollowed base, the draw needed to sit inside the base and be able to be opened.

Timeframe: Twenty hours for the base - which had mininal rafting with the exception of the internal storage, which needed to be removed to allow the draw to be inserted.   The base would require a timeframe in this vicinity to be successful.   The draw took four hours, again with minimum rafting, and this would be a minimum requirement for this to be successful.   The combined time for the print would therefore be twenty four hours.  The printer was running on a 8mm nozzle and has a default setting of 20% infill inside
the print. 
Size: The base stand measures 100mm across and has a depth of 100mm.   The front of the base rises 50mm with the lip.   The rear of the stand was 110mm high and 20mm deep.   The naming letter on the top of the base raised 10mm.   The width of the sides of the base was generally 5mm.   The draw was of relatively similar dimensions.   It was 80mm and 100mm deep with a width of 3mm for the sides.   This was slightly smaller that it could have been.
What we would do differently: The students designed the draw to be somewhat loose as she was wanting it to be easy to open and close the draw, it could have been slightly larger to create a bigger fit, otherwise the design relative to the brief and challenge was extremely successful.
Next Steps for Student: To move onto other projects.  This project has been completed and completed to an extremely high standard, and while there are some very slight minor adjustments to be made the print itself is working extremely well.
