Bambu Lab’s MakerWorld is now one of the highest-traffic STL file sites online. It’s tightly integrated with Bambu Studio and the Bambu Handy app, making it incredibly easy to browse, download, and print straight from your phone without touching a slicer.
That convenience is a big reason so many Bambu Lab owners rely on MakerWorld every day.
But if you’re willing to slice your files on a PC or Mac, you can open up a whole new world of models beyond MakerWorld. There are many other free and paid STL sites with huge libraries of printable designs — and every one of them works perfectly with your Bambu Lab printer once sliced in Bambu Studio.
Here are five of the best alternatives worth exploring.
1. Printables (by Prusa)
Printables.com has exploded in popularity thanks to its clean interface and large community of designers. Models are well-categorized, and you can filter by printer type, material, or popularity.
- Strengths: Huge library, strong community, detailed print settings.
- Best for: Everyday print projects, reliable files with plenty of user feedback.
2. Thingiverse
Thingiverse is one of the oldest 3D model libraries online. While it’s a bit outdated and messy, it still hosts millions of free STL files.
- Strengths: Massive archive of free designs.
- Best for: Digging up older models and niche designs you might not find elsewhere.
3. Cults3D
Cults3D blends free and premium STL files, including a lot of unique, artistic, and niche designs. You’ll find everything from practical parts to cosplay props.
- Strengths: High-quality designs, mix of free and paid.
- Best for: Makers willing to pay a small amount for premium, creative designs.
4. MyMiniFactory
MyMiniFactory is especially strong for tabletop gaming, figurines, and collectibles. It has a curated library with guaranteed-to-print files.
- Strengths: Curated content, great for miniatures.
- Best for: Resin printers, gamers, and hobbyists.
5. Thangs
Thangs.com is more than just a model library — it includes a 3D search engine, so you can find STLs across multiple sites. It’s growing quickly and has a slick interface.
- Strengths: Search engine + collaboration tools.
- Best for: Power users who want to track, remix, or share files across platforms.
Final Thoughts
Bambu Lab’s MakerWorld is convenient and will probably remain the go-to site for most owners thanks to its app integration and one-click printing. But if you’re open to slicing on your computer, you’ll unlock a much wider range of free and premium STL files from other communities.
