Here is the 3D printed case I designed. It was ordered through Shapways. Turned out great, need to add a mm or 2 here and there for some nicer clearance, but it works as expected. LEDs show through as well. Its a screwless design.

Spot for USB charging, and a small opening for the on off switch. So it can't be turned off by accident, you need a pin or small object.

Charging, and other LEDs show through the case.

Next step for this project is to send it off to the programmer.
