Ratchet Wheel V1

implemented unverified

Ratchet wheel: an asymmetric sawtooth ring in the section itself — the steep face locks, the ramp slips — extruded flat with a square (or round) shaft socket. Honesty out loud: this is the WHEEL; the sprung pawl (flexure + fatigue) is its own iteration — pair with a hardware pawl meanwhile.

Built from a real example — orbit to inspect.
