Feels like most high quality results are on printables these days. Thingiverse used to be the go-to so they’ve got a lot of models from the early days, so it’s worth checking.

Makerworld seems to be drawing a lot of the newer crowd due to their huge sponsorship push on influencers, so they have a growing audience as well.

If you’re looking for a functional part (not strictly art or models) it’s probably on one of those three.
