Articulated Joint Piece

A mechanical knuckle that replaces the index finger's middle joint: two brass collars sealed over the flesh stumps either side of the joint, a hinge barrel bridging the gap between them, so the finger bends at the machine. Replacement on the base hand.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
