Anyone know of any good sites for (good) STLs of the popular tabletop/wargaming miniatures?

And, more importantly, anyone have any good experiences with them? My gut would be that the vast majority are pointless in FDM and require the granularity of resin. But I have also seen some wild prints that take advantage of ridiculously thin layer sizes to have insane detail. And, if it isn't a complete fool's errand, this would be a fun set of projects to fine tune both my printing ability and my painting skills.
