1 product tracked About Spare Matter
OwlCAD is a free, browser-based parametric CAD editor built for 3D printing. Combine shapes with booleans, extrude and revolve sketches, add fillets and chamfers, and change any dimension later: the model rebuilds from its history. A print check looks for holes in the mesh, thin walls and overhangs. Import STL, 3MF, OBJ, STEP and OpenSCAD files; export STL, 3MF, OBJ, GLB, STEP, DXF and SVG. Nothing to install, and projects are private by default.
