Where to find free STL files (and how to tell they’re really free)
Most 3D printable models are free to download. The trick is knowing where to look, and telling a genuinely free model from one that’s paid, limited or copied from someone else.
Three kinds of sites
Nearly every model you’ll find comes from one of three kinds of site. Knowing which kind you’re on tells you what to expect.
- Free libraries, such as Thingiverse, Printables and MakerWorld. Designers share models for anyone to download, mostly at no cost. Some also have paid or special sections, so look for the price on each model.
- Marketplaces, such as Cults3D and MyMiniFactory, where free and paid models sit side by side. They’re strong on detailed figures, miniatures and cosplay, where designers often sell their work.
- Printer makers’ libraries, such as Creality Cloud and MakerWorld (run by Bambu Lab), which are tied to their own printers and apps but open to everyone.
Search engines, including Yigo, don’t host files at all: they search these sites for you and send you to the model’s own page to download it.
Search for free models only
On Yigo, search for anything, then set Price to Free. Every result then comes from Thingiverse (where everything is free) or is marked free on Cults3D. Creality Cloud doesn’t say whether its models are free, so its models are left out while that filter is on. Many of them are free, so it’s worth a look without the filter too.
How to tell a model is really free
A few quick checks before you download:
- Look for the price on the model’s page, not just in the search result. Some sites show a free preview picture for a model that costs money.
- Check who uploaded it. The same model sometimes turns up on several sites, uploaded by people who didn’t design it. The designer’s own page is the safest place to download from, and the one that gives them credit.
- Read the license. “Free to download” doesn’t always mean “free to sell prints of”. Our guide to model licenses explains what each kind allows.
- Look at other people’s prints. Photos from people who printed it (often called “makes”) show the model works, and how it looks in real life.
Be wary of “free” downloads of paid models
If a model that costs money on the designer’s own page is offered free somewhere else, it’s almost always been copied without permission. Downloading it takes money from the person who made it, and files from unknown sites can be broken or bundled with things you didn’t want. Stick to well-known sites, and download from the designer’s page.
Say thanks
Free models exist because designers share their work. If a free model worked well for you, post a photo of your print on its page, or leave a like. It costs nothing, and it’s how designers know their work is appreciated.
