robotic finger 3d model

Create a detailed 3D mechanical render of a single robotic gripper finger. IMPORTANT: Generate ONLY one finger. Do NOT create a full U shape. Do NOT mirror the part. Do NOT include a second finger. This is a single half-U curved arm only. GEOMETRY: The part must look like half of a U shape. Open curved structure. Arc angle: approximately 70–80 degrees. Inner arc radius: about 35 mm. Distance from pivot center to fingertip: about 50 mm. The curve must remain open and not close into a full U. BASE / PIVOT: Include one circular pivot hole at the base. Pivot hole diameter: 5 mm. Add a reinforced circular boss around the pivot hole. Boss diameter: about 16 mm. Base thickness thicker than the rest of the finger. BODY: Finger width: about 15–18 mm. Body thickness: about 8 mm. Outer surface flat and clean. Inner gripping surface slightly textured. Fingertip slightly rounded. No hook shape. No second curved arm. STRUCTURE: Add visible reinforcement ribs near the pivot. Lightweight mechanical design. Clearly engin
