robotic gripper 3d model

Create a functional mechanical 3D model of a small robotic gripper based on an SG90 servo, inspired by a fully 3D printed linkage-style gripper. Design: - Compact gripper with two opposing fingers - Each finger rotates on a pivot pin (hinge joint) - Central linkage connects both fingers to a single SG90 servo horn - Servo rotation drives symmetrical closing motion - Include mounting cavity for SG90 servo (tight fit +0.3mm tolerance) - Use standard servo horn geometry for connection Mechanism: - Use simple link arms (no gears) - Convert rotational motion into synchronized finger movement - Include holes for M2/M3 screws or printed pins Structure: - Lightweight with cutouts - 2.5–3mm wall thickness - Reinforced around pivots and horn interface Constraints: - Fully 3D printable - No supports >45° - Clean CAD style, functional not decorative - Output as separate parts (fingers, base, linkage)
