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.
Above: The stand in use with draw in place
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.
Above: The completed design with draw in place
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.

3D Printed Storage Stand w/Drawer

Challenge:  Produce a stand, with drawer storage that is personalized.
Background: Student wanted to produce a personalized, individualized storage stand, with a working drawer.  The drawer in this print came as an 'off print' from the 'horse head' drawer.   Wanting to use this draw for another project it was given to a student who was tasked with producing a storage container that fitted with the original draw.   The student was able to produce the storage part of the design (shown clearly in black) that matched perfectly with the drawer at the first attempt.  Following this, the student designed a Alvin and the Chipmunks design (sourced from online on Tinkercad) to mount on top of the design.   The student concerned with this design is nine years old, using a 3D Printer for the first time in the classroom (since in New Zealand starts school in February we are looking at a four month time frame.
Level of Difficulty: Medium-High.  This print is involving a series of prints, with the drawer and the base working in conjunction with each other.   If the draw was not perfectly working in unison with the storage box then the entire design would not work.
Time frame:   There are a number of component parts to this print. 
The black back storage base took sixteen hours to print.   The drawer that is grey, inserted in to the base took three hours to print.   The 'Alvin and the Chipmunks' design to be mounted on the front of the design took three hours to print.  On this basis for the entire print from start to finish was twenty two hours.   Some adjustment would need to be made to the design (see below) to replace the
lettering and the design on the back of the storage box.
Size: The base of the design (black PLA) was 145mm long, 100mm wide and 20mm high.  At the back of the design the base was 80mm high.   The drawer (grey PLA) 85mm wide, 115mm long, 17mm high and between 10mm and 25mm thick.   The Alvin and the Chipmunk part of the design was essentially 70mm across and 50mm high. 
What we would do differently: Part of the design did not work.  We had discussed with the student not putting words on the rear of the design, below the unicorn design (see left).   The removal of the rafting on the design was not possible without removing some of the lettering.    The lettering should have been printed separately (almost certainly it would have been with a different PLA) and then super-glued onto the design.   The student has also considered to put her name on the top of the design in front of the Chipmunks.
Next Steps for the Student: The student has essentially mastered this design, with the exception of the lettering on the base of the design.   The student could look for additional ways to open the drawer.
