33 Best Sites for Free STL Files & 3D Printer Models in 2019

Check out our 2019 collection of the 33 best sites and search engines to download free STL files and 3D printer models in other 3D printable file formats.

Below, you’ll find a selection of the best 3D printing websites, model repositories, marketplaces and websites that offer free 3D printer models to download. Each lets you browse a large choice of 3D printing designs to print at home.

Some of these sites also include storefronts for selling 3D printing designs. So if you’re a 3D modeler and fancy making some spare cash, these are perfect platforms for showcasing your work and selling it.

To rank the 3D model repositories, we use an equation accounting for the total number of 3D printable models on a site (determined by some sneaky Googly magic, and counting for 95%), plus a little tie-breaker juice from the site’s popularity (Alexa Traffic Rank, counting for 5%).

If we have missed your favorite site for free STL file downloads, please let us know in the comments, and we’ll add them in a future update.
