OpenSCAD 2021.01 (Debian 13 default) is single-threaded CGAL. The Manifold backend, available in OpenSCAD 2024+, parallelises CSG operations and gives massive speedups on multi-cell holders. Bench on this LXC (6 cores), realistic params: 6x12 (72 cells): CGAL 3.14s -> Manifold 0.08s (37x) 10x20 (200 cells): - 1.41s 15x25 (375 cells): - 1.97s Installation steps performed on the server (manual, not in this repo): wget https://files.openscad.org/snapshots/OpenSCAD-2026.04.26-x86_64.AppImage ./AppImage --appimage-extract (no FUSE required) ln -s squashfs-root/AppRun /usr/local/bin/openscad-nightly Code changes: - holder.py: new OPENSCAD_BACKEND env var (default "Manifold"); appends "--backend Manifold" to the openscad call when set. - deploy/busbar-designer.service: points OPENSCAD_BIN at the extracted nightly and sets OPENSCAD_BACKEND=Manifold. Real-time progress percentage was investigated but not implemented: OpenSCAD has no headless --progress flag, so live % from the CLI is not feasible. With Manifold making renders sub-second to a few seconds, the existing indeterminate progress bar + elapsed timer is sufficient.
