I think the one I use the most is printables for mechanic parts and cults 3d for minis. I used to use mainly myminifactory, but they added a managing fee and that’s made me avoid the platform since you pay a bit extra than the published price.

I’ve been trying to avoid makerworld, and creativity cloud since they seem to go in the direction to make it slowly more closed.

Thingiverse was fine, although it seemed a bit abandoned, but if you were looking for older models sometimes it’s the only place.

I think it will be fine for a year or so, but they will push some kind of subscription or premium features.

The community on thingiverse used to be more about sharing and open source, and that seems to have moved mainly to printables. At least we have that option (for now).
