The prompt
Create a parametric 3D CAD model of a hydraulic aircraft wing and movable flaperon based on the reference sketch. **Wing dimensions:** - 240 mm chord, 120 mm span, 48 mm thickness. - Rounded leading edge, curved upper surface and flatter underside. - Separate 60 mm rear flaperon with a hinge near the upper rear edge. - Flaperon must rotate approximately 30° downward. **Hydraulic mechanism:** - Design an internal horizontal mounting compartment for a REAL InJ/Light 60 ml syringe, with its nozzle facing forward and plunger facing the flaperon. - Design an external removable cradle for a REAL KL MED 20 ml syringe. - Connect both using real flexible tubing routed through the underside of the wing. - DO NOT model syringes or tubing as printable parts. - Instead, create accurately sized, hollow mounting spaces with adjustable dimensions, retaining clips and enough clearance for insertion and operation. - Leave both syringe plungers accessible and unobstructed. **Linkage:** Include a control horn attached to the flaperon and a short pivoting linkage connected to the internal syringe plunger. The syringe must push the linkage to rotate the flaperon downward and allow it to return. **Construction:** Include a removable cutaway panel exposing the internal syringe compartment, linkage and hinge. Keep the wing, flaperon, linkage, hinge and mounting clips as separate printable components. **Printing constraints:** Printer build volume: 256 × 256 × 256 mm³. Ensure every printable component fits. Include assembly features and practical clearances. Make all important dimensions parametric, particularly syringe housing dimensions, plunger travel, linkage length and hinge position. Prioritise a simple, functional school demonstration. Do not create dummy syringes, fake tubing or electrical wires.
