How it's made. Seven links in PLA - a 90 mm round base with a turntable, a shoulder block, a 130 mm upper arm, an elbow, a 110 mm forearm, three short wrist joints and a gripper whose fingers slide in a rail - joined by clevis-and-tang hinges on 6 mm pins printed with a 0.15 mm interference, so each joint turns with a firm push and stays put. The joint caps carry a raised ring, the way the real ones do. Every link prints on its flat side, no supports. The name stands 1 mm proud on the base's front in a second colour. About 320 mm at full stretch.
