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.

    2mm is obviously too small for a grub screw. You’re going to need a brass adapter or glue. Either way, it’s probably not coming off (easily) when it’s on there.
