3D model — V1
The exact V1 build geometry: six Ø10 mm edge spars on a 100 mm regular tetrahedron, four LW181 vertex coils on their outward rays. Drag to orbit, scroll to zoom. Generated parametrically from the build canon (build/cad/k4_model.py) — the same dimensions the printable STLs carry.
Printable parts (STL): spar · screen half-shell · vertex coupler · coil cradle. Source: build/cad/.
