Magneto

Originally, I wanted to create a magnetic perpetual motion machine, but that didn't work out, so at least this model was created. It's a hybrid of a fidget, a spinner, and I don't know what else. Have fun with it as you want, one can only rotate, it is also fun to find the point between the attractive force of the magnets.

Assembly instructions:
Print both gears, then magnet holders-16pcs, axis and knobs.
I recommend drilling all the holes so that the holders and magnets go firmly into the holes, the holes in the gears with a 4.5 mm drill and the holes in the holders for the magnets with a 5 mm and 8 mm drill. I therefore chose such a procedure to hold the parts firmly.
You can also print holders with the same dimensions, I made them for magnets that I had at home.

Orient the magnets so that they attract each other - the outside with the inside

I also prepared versions of gers with 8, 16 and 24 teeth, but the 8-tooth one holds best in the hand

I recommend magnet size 5x3mm or 8x3mm, or their combination, as shown in the pictures. You will also need 2 bearings 608zz.

Filaments used: Prusament PLA Viva La Bronze
                             Prusament PLA Galaxy Silver

For Czech-Slovaks there is an excellent website for magnets www.unimagnet.cz - a large selection, fast delivery and a nice gift

In case of problems when slicing 3mf files - if holes are missing in the parts, I recommend using the Prusaslicer
