As of March 30 the PrusaPrinters.org domain points to the new Printables.com. You can read all about it in Prusa's blog here: https://blog.prusa3d.com/prusaprinters-org-is-now-printables-com-ultimate-database-of-3d-models-for-everyone_66880/. I recommend anyone looking for a good source of 3D models to go over and give it a try. As having tried serval different model hosting sites Printables is by far my favorite.
