About OpenSCAD
OpenSCAD creates precise 3D models from a scripting language — perfect for parametric parts, mechanical components and 3D-printing designs where numbers matter more than sketching.
OpenSCAD is completely free and open source (GPL-2.0+) — no trials, no subscriptions, no locked features. Always download from the official website to avoid bundled malware.
