## 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 published dimensions (no free picture of the craft).

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 2026-10-26, and NASA Science's resources have none of this craft; the agency pages were searched, and no agency model of it under usable terms was found); no ESA picture or model is in the file: ESA's pictures (CC BY-SA 3.0 IGO) and a visitor's photographs of the model (CC BY-SA 4.0) are share-alike and were looked at only, for the layout
