The prompt
Modify the existing curved UAV landing gear design into a lightweight optimized design. Keep the same overall geometry and dimensions. Design requirements: Mounting plate: 60 x 45 x 4 mm. Curved landing gear strut: approximately 180 mm long. Wheel diameter: 60 mm. Add 3 to 4 elongated oval cutouts along the curved strut for weight reduction. Add two circular weight reduction pockets in the mounting plate, away from mounting holes. Use a gradually tapered curved strut. Maintain sufficient material around all mounting holes and wheel axle connections. Use smooth rounded edges and avoid sharp corners. Keep the wheel and axle assembly unchanged. Preserve a continuous structural load path. Generate a complete editable 3D CAD model. Return exactly one valid OpenSCAD code block and no additional explanation.
