## 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 NASA's, the Space Force's and SDASM's photographs of Centaur stages.

built by this project in code (tools/stage-builder/, release 1.4.0 stage r14-m1: stagelib.py and one function a stage in stages.py); no image-to-3D model was used and no published mesh: none of NASA 3D Resources' 1 583 paths is this stage and a web search found no agency or operator model of it (read 2026-10-26)

OURS: where the bulkhead rings, weld rings, lines and avionics boxes sit, the gold blankets' places
