PRELIMINARY - UNPOWERED NONSTRUCTURAL MANUAL FIT ARTICLE ONLY - NOT APPROVED FOR PRODUCTION FABRICATION, CONNECTION, POWERED TESTING, MOTION, OR ENERGIZATION

Project Button · HR-30 whole-body derivative

The first hand now assembles and moves by hand.

This eleven-part, one-to-one development fixture converts the authoritative G01 rack-and-pinion geometry into a physically retainable manual article. It exists to replace guesses with measurements before actuator or production hardware is released.

No G-code is included. The receiving printer must perform scale, support, adhesion, collision and time preflight.

Manual build traveler

Checkboxes are a browser convenience only; they are not engineering evidence. The CSV traveler must be completed and signed separately.

This fixture deliberately widens the palm frame, lengthens the guide proxies, fuses rack/finger/pad proxies and uses a manual pinion. Measurements must feed back into the authoritative whole-body G01 design. Do not install a motor or infer structural, load, grasp, pinch-safety, motion, or energization approval.
