## 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 published dimensions of the arm; compared with NASA's STS-31 photographs (public domain).

built by this project in code (tools/hubble-builder/canadarm.py); no image-to-3D model was used, and no published mesh: NASA's 3D Resources has none of the arm (read 2026-11-03)

## Dimensions

- Length: 15.2 m
- Diameter: 0.38 m
- Upper boom: 5 m
- Lower boom: 5.8 m

OURS: the joint-to-joint lengths 6.0 m and 6.8 m (the booms and their joints' housings), 2.4 m from the wrist to the tip of the end effector, which make the 15.2 m, and every other size, read off the STS-31 photographs
