3D Printed Flywheel Toy Car
I designed this using Google Sketchup to be printed on a consumer FDM printer. The flywheel is weighted with 50 pennies, and when the car is pushed the inertia of the flywheel keeps it rolling smoothly for several feet.
I really put a lot of thought into this project, and there's details on every part that have been added and tweaked to make it all work better. After many revisions I uploaded the files onto Thingiverse (see link).
