I found out Thangs locks print files and comments behind an account when I tried downloading my own files from a different device. I’ve decided to leave the platform and going back to my trusty old Thingiverse. I tried to find something new and better but maybe Thingiverse is just the place to be for now. New links below.
Have you tried Printables? Thingiverse’s interface is just horrible and I only go there as the last option.
printables is ok but i always find 1/20 of the amount of models of thingiverse and some things are straight up missing
Personally I stopped using printables after they allowed proprietary designs.
