The prompt
A 3D printable mechanical robotic right hand mounted on a square base enclosure, FDM optimized, watertight mesh. The design features four mechanical fingers (index, middle, ring, pinky) with visible hinge joints, mechanical pins, and internal routing channels for tendon lines. The thumb is uniquely modified: it is a thick, structurally rigid, non-bending appendage pointing straight forward. At the flat tip of this rigid thumb is a recessed 25x24mm square cavity designed to mount a Raspberry Pi Camera Module. The palm connects to a heavy-duty motorized mechanical wrist joint featuring a large servo bracket designed to pivot the entire hand at a 45-degree angle. The wrist is mounted on top of a compact, vented 120x120mm square base box. The base enclosure features cooling vents, internal standoffs for a Raspberry Pi 5, and a rear cutout for USB and power cables. The aesthetic is industrial, blocky, and biomimetic. Matte plastic material, flat bottom planes."
