The short version: Poly Haven, ambientCG, Smithsonian Open Access, NASA 3D Resources, Sketchfab, Thingiverse and Printables all offer free 3D models in 2026. Poly Haven and ambientCG are CC0, so you can use them commercially with no credit, while Sketchfab models carry their own licences and some are editorial only.
Free 3D models save hours, whether you're dressing a scene in Blender, prototyping a game, printing a part or adding a product shot to a video. But 3D files travel with licences, and the one on a model you found at midnight decides whether it can go into a client project the next morning.
Seven 3D model libraries for render, games and printing
In no particular order:
- Poly Haven: best for clean CC0 models, textures and HDRIs made for rendering.
- ambientCG: best for CC0 materials and models you can ship inside a game.
- Smithsonian Open Access: best for scanned museum objects and history.
- NASA 3D Resources: best for spacecraft, planets and space science models.
- Sketchfab: best for a huge range of downloadable models with a licence on each one.
- Thingiverse: best for files designed for 3D printing.
- Printables: best for another big 3D printing community library.
3D model libraries side by side
| Source | Best for | Licence note |
|---|---|---|
| Poly Haven | Rendering assets | CC0, commercial use, no credit needed |
| ambientCG | Game and render assets | CC0, raw files can go inside your game |
| Smithsonian Open Access | Museum scans | Download, share and reuse without asking |
| NASA 3D Resources | Space models | Check NASA's usage guidelines |
| Sketchfab | Variety | Each model has its own licence, some editorial only |
| Thingiverse | 3D printing | Each design has its own licence |
| Printables | 3D printing | Each design has its own licence |
Licences change and vary per file, so check the model page before you rely on any of this.
CC0 models from Poly Haven, ambientCG and the Smithsonian
Poly Haven is about as open as it gets. Its licence page says all of its assets are licensed as CC0, which is effectively public domain, and spells out what that means: you can use them for any purpose including commercial work, you don't need to give credit, and you can even redistribute them or include them in a product. ambientCG uses the same CC0 licence and adds a practical line for developers: you can include the raw files in your project, for example a video game.
Smithsonian Open Access is the one most people haven't heard of. The Smithsonian says you can download, share and reuse millions of its images without asking, with more than 5.2 million 2D and 3D digital items available, and a viewer called 3D Voyager for viewing, interacting with and downloading its 3D content.
Teachers and developers get extra tools. The Smithsonian points to its API and GitHub repository for anyone who wants to bring its open data into a project, and to the Smithsonian Learning Lab for building lesson plans around open access items. If you're making learning materials, a scanned museum object is far more interesting than a generic model, and it comes with a story you can tell.
Sketchfab's editorial licence blocks ads
Sketchfab is a brilliant library, but its licence agreement includes a trap for marketers. Some assets are only available under an editorial licence, and Sketchfab says those can't be used for any commercial or promotional purpose. They're meant for things like news articles, reviews and documentaries. So a model can be downloadable and still be the wrong choice for an ad, a product video or a client's website. Filter for the licence you need before you fall in love with a model.
For 3D printing libraries the same logic applies. Each design carries the licence its creator chose, and some don't allow commercial printing. If you plan to print and hand out or ship the result, read the licence first.
Finding a model you can use in client work
- Decide the use: personal, client work, a game, a print or an ad.
- For commercial work with no strings, search Poly Haven or ambientCG first.
- For real objects and history, try Smithsonian Open Access and its 3D Voyager viewer.
- On Sketchfab, check the licence on the model page and skip anything editorial for marketing.
- Check the file format your software needs before you download.
- Keep the licence text with the file in your project folder.
Props, mockups and learning: where downloaded models fit
Free models are perfect for backgrounds, props, mockups and learning. They're weaker for hero products, where you need your own item modelled accurately. If you're still choosing software, start with my guide to the best 3D modelling software for beginners and check whether Blender is free. If you'd rather generate a model than download one, see where to make 3D models with AI for free.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
My advice: build your scene from CC0 assets first and only reach for anything with a more complicated licence when you have to. Your future self, answering a client's question about rights, will thank you.

Frequently asked questions
Where can I get free 3D models for commercial use?
Poly Haven and ambientCG license all of their assets as CC0, which allows commercial use with no credit needed. Smithsonian Open Access also lets you download, share and reuse its items without asking.
Are Sketchfab models free to use?
Many are downloadable, but each has its own licence. Some are editorial only, which Sketchfab says can't be used for commercial or promotional purposes.
Can I put free 3D models in a video game?
ambientCG says you can include its raw files in your project, for example a video game, and Poly Haven allows its CC0 assets inside products.
Does the Smithsonian have free 3D models?
Yes. Smithsonian Open Access offers more than 5.2 million 2D and 3D digital items, and its 3D Voyager viewer lets you view, interact with and download 3D content.
Do I need to credit free 3D models?
Not for CC0 assets from Poly Haven or ambientCG, though both appreciate it. Other libraries depend on the licence attached to each model.
Where can I get free 3D models for 3D printing?
Thingiverse and Printables are the two big community libraries for printable designs. Each design carries the licence its creator chose, so check it before you print copies to hand out or ship.
