thingiverse
A small easy to build motor. You will need a skate board bearing, 3/16 brass pipe, a few random screws and a spring. A large washer about 2" with a 3/8" hole in it can be used as a flywheel, might want 2 or 3 of them. Take time to polish both the cylinder and pedestal face for the best performance.
