Thingiverse is the world's largest repository of 3D printable files. Since its launch in 2008, the site has accumulated over 2 million free STL files, leaving its competitors far behind.
Operated by premium 3D printer manufacturer UltiMaker, Thingiverse boasts a vibrant community of professional makers who offer free STL files across various categories and complexities.
The website features powerful search and filtering tools for quick results.

Creators can upload their models to share with the community for free, as there is no option to monetize creations on the platform.
Once logged in, you can share tagged 3D printer models in your personal collection or with specific user groups.
These groups are a great way to connect with like-minded makers.

Key Feature: Thingiverse is the go-to source for free 3D printing files. Thanks to the website redesign, it is even more enjoyable to use and browse.
Recently,Thingiverse added a newly curated Discover Thingiverse feature to highlight creators and their designs.
 

 

Printables
With its iconic 3D printer designs, Prusa Research set new standards for FDM 3D printers.
The company also offers open-source software (PrusaSlicer), a filament brand (Prusament), and the meticulously organized file repository Printables (formerly prusaprinters.org), covering all bases.

Its free models currently number over 747,000 and are available for download as STL files.
They can be used with all FDM machines. Some models offer pre-sliced G-code for Prusa machines.

Launched in 2019, the website has grown rapidly while maintaining high quality standards.
The site offers themed 3D design contests and official branded accounts from Paramount Pictures, Arduino, Raspberry Pi, World of Warships, and more.

Key Feature: Printables is a friendly space for the maker community, offering the latest and greatest models.
Contests and designer memberships allow the community's creative potential to shine.

MakerWorld
Bambu Lab's MakerWorld file repository is quickly becoming a top destination for 3D printing enthusiasts.

Despite being a relatively new platform, it already offers a rapidly growing collection of high-quality 3D models, a large number of multi-color models, and a balanced set of features.

MakerWorld's standout features include a user-friendly interface that makes it easy to browse and download its 3D models.
Similar to Prusa's Printables repository, themed contests activate the community's creativity.
They also offer a reward system that allows users to earn points, which can be exchanged for tangible benefits: for example, users can use tokens to boost other users' points, which designers can then redeem.
Finally, "MakerLab" allows users to create and customize specialized 3D models, such as keychains, vases, signs, and even more open parametric models, using an OpenSCAD-based design tool.

The website includes search and filtering tools to help users quickly find what they're looking for. For creators, uploading models and sharing them with the community is simple and intuitive.
Logged-in users can create personalized collections and join user groups to connect with other makers.
These groups provide a collaborative space to share ideas, solve problems, and inspire new projects. If you own a Bambu Lab machine and want to print a specific model, it's almost a one-click printing experience thanks to cloud slicing and common print options (e.g., switching printers, changing materials, copying quantities).

Key Feature: MakerWorld has become an excellent source for free and high-quality 3D printing files, with a sleek design and an easy-to-navigate interface.
If you own a Bambu Lab machine, you can select and print designs with just a few clicks. The added monetization options make it an excellent choice for creators looking to profit from their work.

Cults
Operating from France, Cults is a marketplace for 3D printer files where designers can sell or share their STL files.
Cults' 1,700,000+ 3D printable models are generally of high quality. According to the company, over 600,000 models are available for free download.
They have also recently expanded their offerings with laser cutting and CNC design files.
Users can follow their favorite designers and receive instant updates when new creations are published.
