Are the models free?
Yes. Files in the library are free to download. The license attached to each model determines how you can use, modify, or share it.
Do I need an account to download?
No. Browse a model and choose a file from its download panel. Accounts are used to manage models; public registration is not currently available.
Which file formats can I find?
Models can include STL, 3MF, OBJ, STEP, STP, and ZIP files. Availability varies by model. Extract ZIP archives to access the files inside.
How do I preview a model in 3D?
On a model page with an STL file, open the 3D viewer in the image gallery. Rotate and zoom to inspect the design, and use the file selector when there is more than one STL.
Does every model work with every printer?
Compatibility depends on the model dimensions, geometry, material, and your printer. Review the description and inspect the model in your slicer before printing. There is no universal print setting for all downloads.
Can I sell prints or share a modified file?
Check the exact license linked on the model page. Free downloading does not automatically grant every kind of reuse. If your intended use is unclear, ask the rights holder before proceeding.
Why will a file not open?
Check that the download finished, extract it if it is a ZIP, and confirm your application supports the file extension. Try importing the file through the application’s import command. If the file still fails, report the model and filename through the Contact page.
How can I contribute a model?
Publishing requires an account. If you have one, sign in to manage your own models. Otherwise, use the contact details, when available, to ask about contributing.
Still need a hand?
Include the model link, filename, and what happened so the issue is easier to investigate.
