This is my last minute attempt for the Develop3D Make a Bot Comp entry.
The idea came from the ball bearing model I printed a while back, and I applied the concept to every joint in this robot design.
The model should be able to print in one hit, with all joints rotatable and movable.
Overall size - 200mm x 200mm x 140mmH.

200mm x 200mm x 140mmH
Has to be printed on printers with larger build plate.
Try not to scale it down to fit smaller printers because that will affect the tolerance around the ball bearings.
