The prompt
Design a compact 3D printable Robo Football robot chassis. Requirements: - Maximum size: 180 mm × 180 mm. - Lightweight but strong construction. - 8 black 5 kg micro servo motors. - Arduino Nano mounted in the center. - PCA9685 16-channel servo driver mounted above the Arduino. - Power supply: 3 AAA batteries with an accessible battery holder. - Servo wires should be routed through built-in cable channels. - Include mounting holes for all electronic components. - Add removable top cover for easy maintenance. - Four legs, each driven by two servo motors (8 servos total). - Low center of gravity for better stability. - Designed specifically for Robo Football competition. - All parts should be optimized for FDM 3D printing without support whenever possible. - Use M2 and M3 screw holes where needed. - Export as a parametric CAD model.
