## 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 SpaceX's published dimensions; compared with SpaceX's CC0 photographs.

built by this project in code (tools/falcon9-builder/falcon9.py, on release 1.4.0's stage builder); no image-to-3D model and no published mesh: none of NASA 3D Resources' paths is a Falcon 9 and no operator model of it was found (read 2026-11-03)

## Dimensions

- Height: 41.2 m
- Diameter: 3.66 m
- Interstage: 4.4 m
- Engines: 9

OURS: the interstage's 4.4 m, the tank rings, the leg and fin shapes (a single strut with braces; a lattice of 5 by 3 cells 1.5 m across), the reach of the legs (a foot about 9 m out, so a span near 18 m: not read in a source this release), the soot is not drawn
