robotic finger 3d model

Design a single mechanical robotic gripper finger. This is ONLY one side of a two-finger gripper. Do NOT generate a full U shape. Do NOT mirror the part. Do NOT include a second finger. GENERAL GEOMETRY: The finger must be a single curved arm. It must represent exactly half of a U shape. It must not form a closed curve. It must be an open arc segment only. DIMENSIONS: Total arc angle: 75 degrees only. Arc radius (measured from pivot center to inner curve centerline): 35 mm. Distance from pivot center to fingertip end: 50 mm. Maximum width of finger body: 18 mm. Thickness of finger body: 8 mm uniform. Base thickness at pivot area: 12 mm reinforced section. PIVOT AREA: Include one circular pivot hole. Pivot hole diameter: 5 mm. Pivot hole must be centered inside a thick circular boss. Boss diameter: 16 mm. Boss thickness: 12 mm. Pivot hole tolerance: +0.2 mm for smooth rotation. STRUCTURAL STRENGTH: Add internal ribbing along the outer curve. Add 2 triangular reinforcement ribs near the pivot base. Inner st
