I want to mount a printed part to a standard 2mm motor axis which doesn’t have any dents or profile. Its just round. If I print at exactly 2mm, it fits for the first few times until it gets too lose and the spinning part sometimes falls off.

    Sand a flat to create a D profile and then use a shaft collar and set screw
