STLGen is a collection of free generators for 3D printing. Each one turns a few numbers into a ready-to-print STL file, so you can get a box, vase, gear or name tag in exactly the size you need without learning CAD.
Pick a generator, change the settings and watch the preview update. Drag the preview to look at the model from any side, and use “Cut open” to see inside it. When you are happy, save the STL and open it in your slicer. “Copy link” gives you an address that brings back the exact same design, so you can bookmark or share it.
The models are computed on your own device. Photos, recordings and text you enter are never uploaded. See the privacy page for details about ads, cookies and the download counter.
