walls.py

FDM-optimised walls that use less plastic and print without support: a cross-braced sparse wall, a corrugated wall, thick-edged thinning walls and triangles, and struts.

watertight

The diagonal braces are held under maxang from vertical so every overhang prints clean; the thinning wall is BOSL2's exact 24-point polyhedron, transcribed and closed watertight.

The sparse lattice fills its 4×100×50 envelope with 12,007 mm³ — 40% less plastic than the 20,000 mm³ solid wall, and it needs no support.
