The 26 Best Sites with Free STL Files

STL is the default file format that is supported by almost all 3D printing software. With the popularity of 3D printing growing day by day, more and more people are looking for free STL files of their favorite 3D printing models.

In this article, we’ll look at some of the best sites for free STL files. These websites have a huge collection of models ranging from D&D minis to full-size car engines. Each website has its own unique set of offerings and there’s something for everyone to find.

A quick explanation

To get the full benefit of this list, it helps to understand the differences between the various websites. We’ve sorted out all the websites in three different categories: Repositories, Marketplaces, and Search Engines.

A repository is a place where you can get a large collection of free STL files. These files are free to download for anyone. Depending upon the particular website, you might need to create an account to download these files. Most of the websites mentioned in this list are repositories.

Marketplaces are websites that let you buy and sell STL files or 3D models. You get access to premium models that you can purchase for a particular fee. Usually, these websites are great places to get premium models and you can even directly request the creator to create a specific model for your needs.

Last, we have included search engines that let you search for a specific model across many sites at once. These websites offer a one-stop solution and take away the hassle of individually searching for the model on different websites.
