Magnetic fidget

Quick and easy print - perfect fit fingers which have to play with something all day long...
Both parts take a neodym magnet, each diameter 5 by 3mm.
Put them in with opposite polarity. Lower part has a hole in the bottom to push the magnet out again if you get it wrong in the first place.

The two parts go together with a 90° bayonet.
Tolerances are choosen to hold the magnets with friction fit and to have easy movement between the parts.
For me I take the parts off the printer and they go together without post processing.

Print upper part with supports touching build plate.
Lower part has max 45° overhang and needs no support.
