Cubby stands on excellent open-source work. The components below power Cubby’s geometry and exports; each is credited here with its full, verbatim license notice as the project’s licenses require.

Bundled & server-side components
gridfinity-rebuilt-openscad
MITThe canonical Gridfinity geometry source. Cubby renders authoritative bin and baseplate exports from this OpenSCAD library unchanged, so generated parts match the published 42 mm / 7 mm Gridfinity standard exactly.

BOSL2 — Belfry OpenScad Library v2
BSD-2-ClauseThe Belfry OpenScad Library is vendored as part of the Gridfinity toolchain and credited here for completeness. (At Cubby's pinned commit the Gridfinity source resolves without it, but its notice is reproduced as required.)

OpenSCAD
GPL-2.0-or-laterThe geometry kernel. OpenSCAD runs server-side only — Cubby renders the Gridfinity source into a watertight mesh on the server and sends you the resulting STL/3MF output. The GPL-licensed binary is never bundled into or shipped to the browser, so the program you receive remains proprietary while the output is yours.

GPL noteWritten offer / corresponding source: Cubby uses an unmodified OpenSCAD build server-side. In accordance with GPL-2.0 §3, we will provide the complete corresponding source for the exact OpenSCAD build we run to anyone who requests it, for a charge no more than the cost of distribution. Email hello@cubby.studio, or get it directly from the upstream project at openscad.org. OpenSCAD output (your generated STL/3MF) is your own work and carries no GPL obligation.
Generated meshes (your exported STL / 3MF files) are your own work and carry no license obligation from the components above. Questions about attribution or corresponding source? hello@cubby.studio.
