The prompt
Create a parametric, 3D-printable educational wing-and-flaperon demonstrator FROM SCRATCH. Use the sketch as the controlling layout: a chordwise internal syringe, external control syringe underneath, flexible tubing between them, and a hinged trailing-edge flaperon driven by mechanical linkage. Do not reuse old CAD. Use millimetres. Wing: 240 mm chord, 120 mm span, 48 mm maximum thickness, cambered airfoil and rounded leading edge. Make the rear 60 mm a separate full-span flaperon. Place its hinge axis spanwise at the wing/flaperon boundary, near the upper rear surface. Include spaced hinge knuckles and a removable pin. Provide neutral and 30-degree-down positions, plus slight upward travel. Set adjustable clearance to prevent scraping. Inside the wing, mount a real RAYS InJ/Light 60 ml syringe, model 60LE, lengthwise along the chord. Point its eccentric Luer nozzle toward the leading edge and plunger toward the trailing edge. Use these editable starting dimensions: 29 mm barrel diameter, 125 mm barrel length, and 0.6 mm radial clearance. These are provisional fit values, NOT verified manufacturer dimensions. Add two removable barrel saddles, nozzle pocket, flange stop, and guided plunger exit. Do not model or print a dummy syringe. Under the wing, mount the real KL MED 20 ml control syringe parallel to the chord, with its Luer nozzle forward and thumb pad accessible aft, matching the sketch. Use 21 mm barrel diameter, 103 mm length, and 0.7 mm clearance as editable provisional values only. Give it separate adjustable flange and nozzle dimensions. Make an open, removable cradle that supports without crushing the barrel. Route a smooth 4.5 mm tubing passage between the external syringe connection and internal syringe nozzle. Include generous bends, accessible ports, and strain relief. Model openings only: no printed tubing, wires, cables, or syringe bodies. Connect the internal plunger to a removable capture yoke around its thumb pad, without drilling or modifying the syringe. Link this to a wing-supported pivoting bellcrank, then a short pushrod and control horn fixed to the flaperon. Use pin joints with spanwise axes. Check linkage geometry through the entire travel, not just at 30 degrees; avoid dead-centre positions, binding, and collisions. Make rod length and pivot holes adjustable. Add a removable inspection panel. Split parts so every printed piece fits a 256 × 256 × 256 mm build volume. Output the fully assembled model, exploded view, separate print parts, adjustable clearances, and motion checks. Prioritise fit, access, and reliable demonstration over cosmetic detail.
