Print-In-Place Tendon Thumb
A two-segment robot thumb, 72 mm long, that prints in place. It has a clevis IP joint with a fused 5 mm pin running in a 6 mm bore (0.5 mm clearance) and two 2 mm flexor/extensor tendon channels that end in a tie window at the tip. The root pivots on an M3 bolt through a 3.4 mm clearance hole, so you can add a tendon-driven thumb to a servo or string-pulled robot hand.
Print-In-Place Tendon Finger
A three-segment robot finger that prints already assembled. It has two 5 mm pin knuckles with 0.5 mm clearance, plus flexor and extensor tendon channels (2 mm bores) for fishing line or Dyneema driven by a servo. It is 18 x 14 mm in section and about 104 mm long, and mounts through a 3.4 mm M3 hole at the base.
