Convert OpenSCAD to STL

Paste or upload your .scad code and render it to a printable STL with the real OpenSCAD engine — running entirely in your browser. Preview the result in 3D, then download. Nothing is ever uploaded.

The real OpenSCAD engine

                    
This runs the genuine OpenSCAD renderer compiled to WebAssembly (openscad-wasm), with the CGAL geometry kernel — the same constructive-solid-geometry math as the desktop app. Your code, your result.

Every byte stays on your device. There is no server, no upload, no account. Close the tab and nothing remains. It even works offline once loaded.

                

                

                    
                    
What is supported

                    
Full OpenSCAD language, the MCAD library (use <MCAD/…>), and text() when you enable fonts. Export to STL (binary or ASCII), OFF, AMF or the CSG tree. Complex models render with CGAL and may take a few seconds.
