3D Printed iPod Case

Challenge - Student who had previously completed the expected introductory tasks was looking to move towards creating more creative and technically difficult print.  He identified that he had an iPod that currently sat on his desk at home when not at use and decided to print a box to use for storage.
Background: Student created the original idea from scratch and as a consequence designed it, measured it and throught about the process and the end product.
Level of Difficulty: Medium.  This was created by a nine year old student however it required a number of compartments and details that required specific measuring and designing.  It was a completely original design from start to finish including a 'drop in lid' and cosiderable rafting which needed to be removed in stages.   The lid and the box were printed separately due to their size.  There was inspiration from this box.
Size: the base was 15cm wide, 10cm across with a depth of 5cm.  The lid was essentially slightly smaller than this so it could drop down into the base.

Timeframe: Due to its size being slightly smaller than the Ultimaker 2 build plate both major pieces were printed separately.  The lid was printed in an six and a half hour print.   The box was more detailed and required ten hours.
Process: Inspiration came from another student in the classroom with thier 'Mothers Box Design'.  There were elements of that design in this, such as the drop in lid.  The student has previously used Tinkercad to produce basic classroom designs and was looking to stretch himself with a more complex design that would also have a practical use.  
What would we do differently: There was not a a signature/name built as part of the design which is something that could have been included.   The student spoke afterwards and it was suggested that there could have been an insert designed into the box that would have allowed a charger cord to have been plugged directly into the box or a dock option to hold it.  The student himself was extremely pleased with the project and the execution of it.

Student Creation: Money Holders

Challenge: Previously students had designed boxes to hold classroom cash as designs from the student.  These boxes had times ranging from 35 to forty hours for the base.  As an alternative the student concerned designed a holder that was a single figure.  This is the same student who had previously designed and created the 'pencil topper' print and design.

Background: The task was to create a holder for the students 'classroom cash' that are rewarded to students for excellent behaviour.  Previous designs were based around a full sized box.

Task: Students to create a workable print that was original and creative.

Original Design in Tinkercad with insert clearly visible

Level of Difficulty: Medium on the basis that the design was up to the students and the detail was dependant on the design.  This is shown further refinement from the 'pencil topper' design.

Issues: None.   The student was able to produce a limited amount of rafting with the project and the print was completed in a single print run.
Size: Length of 6cm (high), width (5cm)
Timeframe: Six Hours on Fast print setting.

Process: The student (who is ten years old) has shown the creativity to create original designs from scratch using Tinkercad and a laptop as creative tool.  He is confident and enjoying the process.  He is developing his ideas around geometric shapes and applying the problem solving.  Design from scratch using Tinkercad, converted to Cura for 3D printing and printed on an Ultimaker 2.
Recommendation: The student has been pleased with the quality of the print and the design of the animal.  There is a clear evidence of his progress using Tinkercad to create animals/shapes and the student is becoming recognised by his peers as a problem solver.  The print time would mean that the print is realistic as a holder for a variety of objects and could be easily modified to hold other objects depending on the needs of the students.
