Marble Machine

thingiverse

This is an entertaining remixed marble machine, albeit somewhat unbalanced, so be prepared to add a support beam and attach it firmly in place. Designed specifically for 3/8 inch steel marbles, it also accommodates some other sizes. To secure the ball carrier to the frame, you'll need a small nail. Kudos to "qrry" for originating this design - check out their profile on Thingiverse (https://www.thingiverse.com/qrry/about). For optimal performance, spin this device to the right and get ready to have fun.
