Standalone generated CAD examples used for demos, visual inspection, and occasional print/export experiments. These models are more expressive than the benchmark fixtures and are not expected to form a systematic test suite.
*.py: build123d generator source for authored models.*.step: canonical generated STEP output..*.step.glb: generated render/selector sidecars paired with STEP files..*.step.js: optional interaction sidecars paired with STEP files.*.stl,*.3mf, and direct*.glb: durable exported/printable artifacts when the export itself is useful as a fixture.
