Prompt
Design a compact, high-efficiency 3D printable whistle keychain for real acoustic performance (~115–120 dB). Size: 60x20x15 mm. Dual-chamber pea-less system with separate airflow channels (each 3.2 mm wide, 1.2 mm high, ~18 mm long, tolerance ±0.1 mm). Include smooth internal air ducts directing airflow to a sharp labium edge (0.3 mm thickness, 15–18° angle, 0.9 mm gap). Add two resonance chambers (20–25 mm) slightly converging for high-frequency amplification. Output openings flared 5–8° for projection. Mouthpiece: oval 8x5 mm, ergonomic. Walls: 1.4 mm external, 1.2 mm internal. Add 1 mm ribs outside airflow zones. Keychain loop: 5.5 mm inner diameter, 4 mm thick. Optimized for PLA, 0.4 mm nozzle, layer 0.16–0.2 mm, no overhangs >45°, flat base, support-free. Clean, watertight, manifold mesh. Style: innovative, aerodynamic, asymmetric, functional sharp edges only at labium.
