## 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 pictures; compared with photographs of the Berkut suit on display (CC0, CC BY-SA, public domain).

built by this project in code (tools/vostok-builder/, release 1.7.2: leonov.py); no agency or museum 3D model of the Berkut suit or of Leonov under a free licence was found (read 2026-11-03): NASA 3D Resources has nothing of it; the downloadable meshes a web search found are sold or personal-use only. So it is built, as the quality bar says, from opened facts and several photographs of the flight-standard suit and the museum displays. No image-to-3D model was used and no published mesh.

## Dimensions

- Height: 1.8 m
- Pack width: 0.33 m

NOT PUBLISHED on any page opened, so READ OFF THE PHOTOGRAPHS and ILLUSTRATIVE: the figure's 1.8 m head to toe in this pose (Leonov was about 1.78 m; the suit adds its bulk), the pack's size, the suit's puffing, every pocket, ring, strap and hose, the chest camera, the pose of the arms and legs (read off the film frame and the posed museum display).
