Crabot, a little project I made over spring break. Top and Bottom parts need to be printed once each, the leg/arm piece needs to be printed 12 times for the legs, and 2 times for the arms (14 times total). Claws 2 times, hips 2 times, and the feet 6 times. The guns are optional prints, but they can be popped into the port on the back. They may need to be sanded to fit properly, but they SHOULD fit just fine (5mm port).
Limbs are tough to attach, but once they're in place they should articulate just fine.
