I bought a bit of 0.8mm CFRP stock along with my tubing order. I think I may use it as a base plate; the circuit board should be separable from the legs to allow easy motor soldering (easy-ish), but I'm hesitant to build the entire base from SLS nylon. So... time for a spacer of some kind.

Might as well include eyes, right? I tried some 1mm thick parts I had lying around from Shapeways and an ultrabright LED shines right through; the 'pupils' in the model should create a distinct shadow (and I can always sharpie 'em from the inside a bit if needed).

I'll need to orient the print so that the pupils are at the top; with luck, the rings from the print process will show as concentric shadows. In any case, they're interchangable even though only one will use its bolt hole due to circuit board asymmetry. One concern--the antenna is right between the eyes on the board. Might need to pull the CFRP back a bit in that spot to avoid blocking the signal.
