## 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; compared with photographs by the Korea Aerospace Research Institute (KOGL Type 1).

built by this project in code (release 1.4.0 stage r14-m4: one script a craft on release 1.3.0 W3-b's part library, lib.py and parts.py, kept with the stage's notes in ~/space-radar-handoff/release-1.4/r14-m4/build), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh: a search for one on 2026-10-27 found none, NASA's 3D Resources has none of these craft, and KARI publishes photographs under KOGL Type 1 (attribution) and no model that was found (read 2026-10-27)
