Fin Ray Compliant Gripper Finger
A Fin Ray-style compliant gripper finger, 94 mm long × 30 mm deep × 22 mm wide, with a 3 mm contact beam, a 3 mm tapered spine and six 2.6 mm cross ribs, so the face wraps around whatever it touches instead of point-loading it. It bolts to any jaw carrier with two M3 socket screws on a 14 mm spacing through counterbored 3.4 mm holes (5.5 mm heads sink 12 mm deep); the part is mirror-symmetric, so print two identical fingers for a two-jaw gripper.
