The prompt
Create a parametric 3D model of a quadcopter frame for long-range cargo missions. The frame is an X-configuration with a wheelbase of 1100 mm (distance between diagonal motor centers). It must be designed to carry a 5 kg payload and integrate HOBBYWING XRotor X6 PLUS power systems with 24-inch propellers. 1. Arm tubes (4x): Outer diameter: 30 mm. Material (for reference): carbon fiber. The arms are straight, arranged in an X pattern. Each arm tube must have a flattened, reinforced section at the inner end for clamping to the central plates. 2. Motor mounts (4x): Integrated into the outer end of each arm tube. The mount must accept the HOBBYWING X6 PLUS direct-tube mounting system. Mounting hole pattern: 4x M4 through-holes. Please use a standard square pattern suitable for a 30 mm tube clamp (e.g., a 25 mm or 30 mm pitch circle/square). The exact spacing can be parameterized. 3. Central frame plates (2x): Two flat plates (top and bottom) that sandwich the inner ends of the arm tubes. Plate shape: roughly rectangular with rounded corners, sized to comfortably fit the four arm clamps and provide a mounting area for electronics (flight controller, battery, payload). Suggested plate dimensions: approximately 200 mm x 180 mm, thickness 2.5 mm (parameterized). Include 4x M3 mounting holes on a 30.5 mm x 30.5 mm pattern in the center for a standard flight controller. Include 4x slots or holes for battery straps (e.g., 20 mm wide slots). 4. Landing gear (optional but recommended): Simple tubular legs attached to the bottom plate. Tube diameter: 20–25 mm. Sufficient height to keep the 24-inch propellers clear of the ground (at least 250 mm clearance from the bottom plate to the ground). Key parameters to expose as sliders: wheelbase (default 1100 mm) arm_tube_od (default 30 mm) plate_thickness (default 2.5 mm) motor_hole_pitch (default 25 mm, to be adjusted) landing_gear_height (default 250 mm) The model should be a solid B-rep (STEP-ready) and structured as an assembly with separate bodies for the arms, motor mounts, and central plates if possible. Prioritize mechanical realism and printability/manufacturability.
