description = """A simplified corner bracket for 20, 30 and 40 mm aluminium extrusions: two flat legs at a right angle, \
as tall as the extrusion, in two leg lengths, without holes. Measured from step.parts' published models (MIT); no maker \
or standard is behind them, so use it as an envelope in assemblies.

Legs along +X and +Y from the origin, rising along +Z. Dimensions and attribution: see the README."""
