Grab Handle V1
implemented unverified
Drawer/door/case grab handle — the first section_sweep archetype: a round bar swept along a planar arc, welded into two flat countersunk screw pads. The bar is probe-verified solid along the WHOLE declared arc; printed pads-down, the bow is self-supporting.
Built from a real example — orbit to inspect.
