|The design shown without the pencil sharpener inserted|
Background: A number of the prints in this series have already been posted and detailed. Some of them have already featured pencil sharpeners or magnets. This was a student who wanted to push themselves with an extremely creative and detailed print. They build the robot that is featured here in the design from 'scratch' using the parts of the Tinker cad main interface that would produce the various features. They then developed the head of the robot to include an opening for a pencil to be inserted into an a second opening to house the pencil sharpener and also allow the waste from the pencil to exit out the mouth of the design. Further printing was to include the facial features of the design to include eyes, which were printed separately with a secondary colour to make them stand out. This student is a ten year old students who has consistently shown outstanding design ability and the idea of creatively making projects that both look appealing and also have a a balance between their size, creation and functionality.

Time frame: Six hours to complete the print at the standard default settings that we currently use and have done for the past four years or so - a 8mm nozzle with a 20% infill for the printing of regular PLA. Given the general factors for the design and creation there was little room for adjustment.
Size: The print dimensions were 30mm across for the feet 50mm across for the body and arms. A separate print was completed for the head. This measured 50mm across and was 50mm high. The dimensions of this required additional work to be completed. (See below).
What we would do differently: The dimensions of the print as specified above created an issue that the print became top heavy. It is requiring an additional print to stabilize itself - while it works exceptionally well and looks commercial it was not built with perfect engineering hence the leaning that is taking place in some of the photograph the next step for the student is to design a stand that is suitable to allow the robot to remain standing up.
