The single biggest content repository for 3D printer models on the internet is Thingiverse, a website operated by MakerBot Industries, the creators of the popular Replicator series of 3D printers. The site is well established and mature, with a huge community of dedicated makers offering free STL files to download in varying categories and complexity. Once you are logged in, you can share tagged 3D models in a personal collection. If you’re looking for cool things to 3D print, this is the best place to start.
The mission statement of GrabCAD is to “help mechanical engineers build great products faster”. The site offers tools that help users collaborate in the development of their 3D printer models. But for the typical 3D printing enthusiast (like yourself), the best part of the site is their large library of 3D printer files — available as free STL files and other formats — created by the largest community of over a million engineers, designers and manufacturers. Besides free STL files, the site offers the free 3D printing software GrabCAD Workbench and GrabCAD Print.
Over 1 million creators upload their 3d models their Sketchfab. It is a great source of user-generated 3D designs, with an emphasis on character design and sculpture. You can use the free 3D models in your VR, AR and gaming projects. Their downloadable 3D printer models are only a sub-category of a larger collection (2 million free 3D models), and these are available as either free STL files or OBJ files (the difference is that OBJ format contains color information for advanced printing). If you’re looking for something unusual then this is the place.
CGTrader is a marketplace to buy and sell 3D designs. They’re not just limited to CAD files, however; the site also offers a nice selection of free 3D printer models to download which can be fabricated on any 3D printer. The 3D printer models are sorted by categories and can be downloaded after signing in.
MyMiniFactory is a community and repository for free 3D printer files. It has close ties with iMakr, an online store that sells 3D printers and accessories. The site offers 3D printer models made by professional designers, with a guarantee that they’ve been quality tested. You can also log a request for a specific 3D printable design that their designers will create and then share. An added bonus is that the site is available in seven different languages. Gaming, gadget and design 3d printer models are strong categories of MyMiniFactory. They also offer challenges for 3D designers on a regular basis; also, they host a great free STL files collection of cultural heritage called “Scan the World”.
Free3D is a great entry point if you are looking for royalty free 3D models you can use in CAD or 3D and game design. The website also offers a smaller collection of free STL files that are tagged as 3D printable. From the looks of it, not every item in the section was 3D printable with an FDM 3D printer – so you might need an SLA printer to make full use of Free3D’s models.
Yeggi is a dedicated search engine that will crawl through many 3D printing websites for 3D printer models. You can also look up some of the popular searches to get an idea of trends the community is currently interested in.

The community blog is an excellent read, too.
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.
US manufacturer Dremel has a curated portal specially for their Idea Builder line of 3D printers. Based on the pretext that the Idea Builder can only 3D print in PLA filament, this selection of 3D printer models is optimized for a frustration-free experience. The free STL files are great to be printed in classrooms, as they also are accompanied by education material for teachers. The sources are diverse too, with 3D printer files pulled in from MyMiniFactory and Autodesk’s (now defunct) 123D series.
YouMagine is a community website operated by Ultimaker, the open source 3D printer company, where users can upload and share 3D printer models.

In a previous incarnation, the Zortrax library was integrated into their Z-Suite software, so it was only available to owners of Zortrax 3D printers.The repository offered plenty of free STL files. The company has now split the library from the software and made it openly available online. That means anyone can browse and download free STL files, and fabricate them on any FDM machine. It’s a canny move, too. Most of these 3D printer models are optimized for ABS filament; makers who wouldn’t ordinarily use the material might be tempted to give it a try.
The name is pretty self-explanatory, right? STLFinder is another search engine for 3D printer files that will crawl the internet, bringing up results for free STL files and 3D printer models.
