Important note: I wasn't able to source anymore affordable high quality bearings for this project. I bought two batches and used up the first batch for this project and threw out the second batch. Do you know the solution?
The whole build is modular and using the spreadsheet in the FreeCAD project file you can visualize your own build. The files are on Thingiverse.
Basically I've ordered cheap 686 open 6x13x3.5 mm bearings (€0.37/pcs) off of Aliexpress and degreased them with purified gasoline. They press fit into the rotator part.
For the magnets, I've used 10x10 cylindrical magnets. They also press fit into the rotator part. The part might crack, but will stay intact and the magnet will not fall out in my build.
