## 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 ESA's and eoPortal's published dimensions; compared with pictures by ESA (CC BY-SA 3.0 IGO) and Neq00 (CC BY-SA 4.0).

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 EUMETSAT publishes no model of its satellites that was found, and ESA's multimedia terms (the ESA Standard Licence) allow use for information and education, not an altered model (read 2026-10-27)
