Rubber Band Pull-Back Car

This is a simple rubber band powered pull-back car. It has few unique pieces and goes together simply, and can be a base to attach other printable car bodies to.

It prints well but requires substantial clean-up, at least on my printer. The ABS slides well on itself but obviously not as well as a bearing. I've found it works better with added weight on top, otherwise it just skips and hops.

I am planning a second version using bearings and a ratcheting system, with a narrower body to reduce from three to two separate prints. This revision will have inset nut slots and magnetic mounts for interchangeable bodies.
