## 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 the operator's published sizes; layout read from the operator's photograph and rendition as eoPortal prints them, looked at only.

built by this project in code (tools/nanosat-builder on the part library of tools/stage-builder/lib.py), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh: NASA's 3D Resources has none of this craft, and no operator of it publishes a model under a free licence (searched 2026-11-07)
