Generate a browser-local OpenSCAD script template for boxes, cylinders, plates with holes, bracket notes, and enclosure notes without running OpenSCAD.
The generator validates dimensions and cutout options before emitting OpenSCAD module text with variables, primitives, difference cutouts, and review comments.
It keeps generated scripts hidden until an explicit action succeeds, then shows the script, result-driven preview, warnings, downloads, assumptions, limitations, references, and related workflows.
