A complex engineering-grade joint hub with multiple red connection points, based on a central rectangular body. The front of the gray body features a precisely-sized, interlocking "female" black engineering plastic socket, textured to accept the squared end of Arm (1). The back of the hub is a complex connection module with two parallel, T-slot type matte red rails on top and an intricate circular-and-square red rear connector plug. Directly below the center of the body is a bottom-facing red connector boss with concentric alignment rings. Rendered with clean, distinct material separation and fine FDM 3D printing layer lines.

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)
