## 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 eoPortal's and ESA's published dimensions; compared with pictures by ESA (CC BY-SA 3.0 IGO) and Don-vip (CC BY-SA 4.0).

built by this project in code (release 1.3.0 stage W3-b's part library, lib.py and parts.py, and one script a craft, kept with the stage's notes in ~/space-radar-handoff/release-1.3/W3-b/build), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh: NASA's 3D Resources and NASA Science have none of these craft; ESA publishes no model of them under terms that allow a derivative (its multimedia terms, the ESA Standard Licence, allow use for information and education, not an altered model); EUMETSAT publishes none (read 2026-10-20)
