## 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 NASA's and De Pontieu et al. (2014)'s published dimensions; compared with NASA's photographs (public domain).

built by this project in code (release 1.3.0 stage W3-a's part library, lib.py, and one script a craft, kept with the stage's notes); no image-to-3D model was used, and no published mesh: NASA's 3D Resources (1 583 paths) and NASA Science's 3D models have none of this craft (read 2026-10-20)

## Dimensions

- Length: 2.18 m

Panels built 1.30 x 0.65 m (the 1.7 m2 the paper gives needs 0.65). OURS: the bus 0.98 m across and 0.46 m long, the tube 0.30 m, the instrument box, every small part
