## 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, DLR renders (CC BY 2.0) and a Planetary Society diagram (CC BY 3.0).

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: JAXA publishes no model of the probe under terms that allow an altered derivative, and NASA has none (searched 2026-10-20); DLR's renders (CC BY 2.0) and The Planetary Society's diagram (CC BY 3.0) were looked at for the layout and are not in the file; JAXA's 1:20 model (photograph CC BY-SA 4.0) and JAXA's labelled views were looked at only. NO JAXA PICTURE OR MODEL IS IN THE FILE
