This is a relatively simple spinning plate i made that uses (once again) a spare 21mm motor i had laying around. I used 2 AAA bateries to power it and there is also a 18,5x6 hole for a switch. You will also need 3 5x10x4 bearings. Before you fit them on the bottom, you will need to do some sanding. For geared parts I recommend higher print quality, but for the bottom it shouldnt be a problem if the quality is lower. To reduce the noise, you can also grease the gears, but avoid doing so with the rail that holds the plate in place. Supports are only necessary for the bottom. The bottom of the bevel gear should be aligned with the edge of the motor mount, into which you can just slide the motor. It should be tight enough for the motor to stay in place, otherwise just glue it in.

UPDATE
26.02.24 - made the rail and teeth on the plate higher and changed wheels to make it more stable and eliminate sliding on the motor mount

• added a hole in the motor mount for a zip tie
• removed the hole for the switch
