Print-In-Place Tendon Robot Finger
A 120 mm, three-joint robot finger that prints as one piece with 16 x 16 mm segments. The pin hinges have 0.5 mm clearance, and there are flexor and extensor tendon channels for 1.5 mm cord or fishing line, with a tie-off hole in the tip. It mounts with four M3 screws through a 32 mm wide flange, so a servo or cable spool can curl it into a gripper.
