Magnetic Gear Wheels
thingiverse
Fridge magnetic gear wheels for children. This is a remix of https://www.thingiverse.com/thing:4097526. Unfortunetely my hotend is magnetic therefore was impossible to put magnet in a wheel center during print. Therefore here is my remix with wheel center consisting of two parts, which are then glued together. Use 15x4mm neodymium magnets for smaller wheels and 15x5mm for bigger ones. I have used original https://www.thingiverse.com/thing:2583482 scad file for exporting whole spectrum of sizes.
