Mid-century structuralist language: the sheet's own thickness and a single fold do the work, with no extra lips, J-strips, or brake setups.

Two gauges on purpose — 3 mm for the load-bearing L and the hook, 1.5 mm for the sconce so the Ø2 mm starburst holes stay at or above material thickness.

The starburst perforation is generated rather than drawn: a Python script emits an SVG preview plus R12 DXF circles for Insert DXF onto the Base Flange sketch.
