Here are a couple of pictures of the finished 3D printed case:
The case has two compartments. One for the Explorer Board + Edison & one for the 2000mAh battery.
They should be arranged as shown on the picture so the battery connector does not get stuck in the case.
There is a variation on the case... a belt clip.
Will probably make it softer / rounder later...
