My original challenge was to have rotating rollers with a self aligning flat on them to help prevent marking of the component. It became a bit too complicated and with more parts progressive errors can creep in. So I decided on this simple design to prove the concept. However after a rethink, I have a simpler solution to incorporate rotating flatted rollers.
