- Thingiverse
Perhaps one of the most well-known repositories, Thingiverse offers a wide variety of both for-sale and free STL files. Its UI is clean and easy to use, and it contains thousands of user-created designs and models, which run the gamut, from toys to tools - Cults
Cults hosts a large variety of STL files, sorted by category, including architecture, gadgets, games, tools, and jewelry. If you’re looking for a file in one of these areas, chances are you’ll find it on Cults - Free3D
Free3D is all about – you guessed it – free 3D files. Not all are STL files, but that doesn’t mean there aren’t plenty to choose from. Here, however, you’ll mainly find STL files geared towards hobbyists or more casual 3D printing users. If you’re looking for professional applications, you may need to look elsewhere - STLfinder
STLfinder lacks the polished overview of other sites out there, but its simplicity is a benefit. Just type whatever you’re looking to print into the search bar (essentially the only thing populating the home page), and you’re good to go - Yeggi
Yeggi is similar to STLFinder, in that it functions predominantly as a search engine for free 3D design and STL files, of which it is home to more than 2 million. Unlike STLFinder, however, searching on Yeggi is a slightly more refined experience, thanks to filters and other options that enable you to better home in on exactly what you’re looking for - Printables
Formerly known as Prusaprinters.com, Printables is one of the fastest-growing STL file repositories. In addition to thousands of downloadable files, the site also has great community engagement, and regularly runs contents to discover and spotlight amazing 3D designs - MyMiniFactory
MyMiniFactory caters predominantly to tabletop miniatures and terrain. It offers a great number of free files, although creators are also able to sell their designs – enabling them to pursue careers as full-time 3D designers
