3D printing projects
Design in your browser, download an STL, and slice it for any printer. Each card shows design time and anything extra you'll need.
Design your own clock hands
Shape the hour, minute, and second hands — export SVG or STL.
Design your own box
Rectangular, hex, or round boxes with lids and compartments. Export an STL for 3D printing.
Design your own lithophane
Turn any photo into a 3D lithophane — export an STL for 3D printing.
Design a 3D keychain
Raised-symbol keychain blank — export STL for any 3D printer.
Design a text flip
Two names, one 3D print — read each from its own angle. Export STL.

Free 3D Printing Projects for Beginners
Each of these projects generates a clean, watertight STL file in your browser — no CAD, no account. The exports are standard binary STL with proper triangle normals, so they slice cleanly in Bambu Studio, Cura, PrusaSlicer, OrcaSlicer, and any other slicer, on any FDM or resin printer.
Plain PLA is all you need to start — white PLA for lithophanes, any color for the rest. Don't own a 3D printer? Many US public libraries have one you can use free with a library card — use the makerspace map link above to find one near you.
