Sheet Metal Tetrahedron
Also inspired by the primitive shapes, we made a sheet metal model of a shape that had been sliced to create voids and compartments within the shape. I picked the tetrahedron and sliced it twice to create an L-shaped piece.
Drawings showing the assembly, surfaces, and volumes of the shape.
Finished sheet metal model.
All connected with spot welds.
If walls could dream... they'd dream of metallic geometry.
