## How it was made

Built in code from published dimensions and photographs, with no image-to-3D generator and no one else’s mesh. 3D model: built by Space Radar from published dimensions and KARI's photographs and render of KOMPSAT-3 (KARI, KOGL Type 1).

built by this project in code (the private tool model-from-images: assemble.py, from a yaml of primitives), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh: NASA's 3D Resources (1 583 paths, read 2026-10-27) has none of these craft, and no agency named here publishes a model of its own under terms that allow one

## Dimensions

- Height: 3.5 m
- Diameter: 2 m

OURS: the hexagon's width (1.73 m across flats = the cited 2.0 m across corners), the split of the 3.5 m into modules, the panels' 1.9 x 1.0 m and their 40 degree fold, every patch.
