Let's print! 

This concept had absolutely zero electronics considerations, but I wanted to know early how it would play out. So, nothing better than a one piece print that you can carry around and test.

I tested it with a 5 year old who was very curious about it and agreed to help me if in return I would show her and let her play with the final concept. Her terms were acceptable. 

Seeing her using the model gave me very interesting insights. The size of the device and the handle are manageable for smaller children, but having the handle to the side does not work well if you are carrying sheets of paper in the back container. 

Another very important insight was to see how children would hold the device. Based on this, I had to raise the speaker a but more to prevent it from being blocked by their hands.
