The STL file collections include face shields and low-cost prosthetics, plus models of various human organs for education and research purposes. This United States government agency for biomedical and public health research offers scientifically accurate or medically applicable models for download.

While this is technically a marketplace, Pinshape is a thriving community which make available quirkier models that range from Star Wars-inspired miniatures to jewelry. As one of the newer community-focused sites, while also aiming to grow into a marketplace, Free3D has some great potential. Multiple language options make for easier navigation and searches.
