3D model description

This fun 3D printed model lets marbles roll down a spiral track and get lifted back up by a mini DC motor. As they fall, the marbles hit small spinning parts on the side, adding a nice touch of movement. You can run it with multiple marbles for a relaxing and satisfying effect. Just turn it on and enjoy the loop!
Marble diameter of 15~16mm (0.6") should be used.
