(Pinshape)

Taiwanese manufacturer XYZprinting has a dedicated 3D gallery of free STL files to download. There’s no digital rights management that we could find, but you have to first register with the site to access the 3D printer files. The majority of items here — about 5,000 models altogether — do not appear to have been printed, given the preponderance of renderings over photos of physical objects. But it’s reassuring to see that they have dedicated repositories for both stereolithography (SLA) and dual-extrusion 3D printing.
