## 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; compared with SpaceX's CC0 photographs and Steve Jurvetson's CC BY 2.0 photographs of the stage.

built by this project in code (tools/falcon9-builder/falcon9.py: the fairing halves; the second stage is the build of tools/stage-builder/stages.py falcon9, the row `falcon9-stage2`); no image-to-3D model and no published mesh (read 2026-11-03)

## Dimensions

- Fairing diameter: 5.2 m
- Fairing length: 13.1 m
- Stage diameter: 3.66 m

Source: Wikipedia, Falcon 9 Full Thrust (https://en.wikipedia.org/wiki/Falcon_9_Full_Thrust), quoting SpaceX: fairing 5.2 m across and 13.1 m long. OURS: the fairing's flare, its ogive and its nose radius (an ellipse-like curve, not SpaceX's), the cut along x = 0 into halves
