Jobot

Print in place robot, takes around 30mins.
Head, arms and legs move.
There is a version with and without antenna.

I've included 2colour files. But you can swap filament at 5.8mm, then back again at 6.2mm for a similar look.
If you change colour at 5.2mm, you can alter the colour of the center of the larger eye and mouthpart (Doesn't show up too clearly in the picture, I used Translucent Blue).
