A ventilated wrist brace built on an imported arm scan.
The scan becomes a solid; a shell with clearance to the skin is offset from it and trimmed by planes and a slit. Holes are laid out by count on the inner face, as many as fit at one hole and one web apart, each sized to the room it has to the edge, and the edges get rounded rims. Every dimension is a named parameter at the top of the document.
