Multifile bracket

easy tier · create

The request

Make a plain L-bracket: two flat rectangular legs at 90°, each leg 50mm long, 40mm wide, 4mm thick. No holes, no fillets. Split the implementation across at least 3 files — for example one file for the leg dimensions, one for the geometry-building logic, and the entrypoint that ties them together and declares meta/parts/views.

What the AI judge checks

Measured checks

split across at least 3 files (gate)
