This is a fully 3D printable bevel gear assembly, which once together spins easily. Fun printing project for working out how gears work or even use it as a fidget toy. To assemble simply align the two gears with the holes on the base, then insert the pins with a small amount of force. The gears will now hold each other in place and should spin freely.
