Recently I wanted to learn painting my printed parts. While painting the first part I recognized that a mechanism to rotate the painted object without directly touching it would increase the quality greatly - wohoo so suprising...
Therefore I designed this part. It consists of two separate printed files. In addition you need a 608zz bearing for assembly.
Both, top and bottom plate are 160mm in diameter. The assembled plate is less than 20mm in height. Because of the bearing the top part can be rotated without great force but the friction introduces enough friction to stop the movement relatively fast.
Because of variance in tolerance of different printers (and my cheap 608zz bearings, too), I provide different shaft/hole sizes, decoded in filenames. If requried I can provide other sizes, too.
I may add a motorized version in the future which allows to control the rotation with a buzzer.

Depending on your print settings, the shaft of the top part may have no infill. This may result in cracks on the shaft during assembly, based on your printer tolerance.
