this is a final project for a week long CAD class to make a key chain. It has not been printed and could, hypothetically be made to move the pedals and wheel together. I can post the individual parts if there is interest. It has not been optimized for 3-D prints yet. So far it has failed to print on mine because it doesn't do supports very well, so the wheel did not have enough surface area to stick late in the print. let me know if it succeeds for you!
