Magnetic Gears

Gears with holes for 3x6mm magnets that can go on the back of the models to hold them in place. They are print in place and only need the magnets inserted at the end. The magnets should be super glued in place to prevent them from having a chance of falling out. The magnets will need some pressure to fit them in place, which helps add a friction fit to the super glue. Included is a small, medium, and large gear. They each require 2, 3, or 4 3x6mm round magnets to hold them in place. A little silicone or other lubrication can help them spin easier but it is not required.
