prosthetic arm 3d model

A single bionic prosthetic right arm, isolated, no body, no torso, no head — just the arm from shoulder to fingertips. Sleek matte-white armor shell panels over the upper arm, forearm and hand, with exposed dark gunmetal-grey articulated joint mechanisms at the elbow and wrist. Five fully articulated mechanical fingers with segmented phalanges and visible knuckle joints, plus an opposable thumb. High-end cybernetic prosthetic aesthetic, clean and seamless. Straight neutral pose, arm extended, fingers slightly relaxed. Plain background, single object.
