Free STL models to download and explore

Looking for an STL download to test a viewer or slicer? Choose an original model below, check its stated dimensions and read the model license. No signup is required.

Use the examples

Import these models as millimeters. Their geometry is checked for closed edges and consistent winding; no physical print test is claimed. Inspect each in the viewer and your slicer before printing.

Free model license

You may download, modify and print these six original models for personal or commercial use, including selling physical prints. Attribution is appreciated but not required. Do not claim our original source files as your exclusive work or imply endorsement. Files are provided as-is.

Create your own with PNG to STL and the outline guide.

Try one model before scaling a larger print

Open the 20 mm cube or another simple sample in your slicer and compare its dimensions with the size listed here. You can get each example STL free of charge under the published license. Use the samples to check units and practice a workflow; a simple sample does not validate a functional or safety-critical design.
