Prompt
Modify only the internal geometry while preserving the outer body. Follow the reference drawing exactly. Create a functional aerodynamic wind whistle with a long Venturi nozzle, sharp 15° labium edge, 0.4 mm feedback slot, large teardrop Helmholtz resonance chamber, smooth airflow channel, and exponential horn outlet. The airflow must pass through Venturi → Labium → Helmholtz chamber → Horn. All chambers must remain hollow and connected. No decorative details. No solid filling. No simplification of internal passages. Maintain engineering accuracy. Split into two printable halves with 2 mm wall thickness, alignment pins, screw holes, support-free FDM design for Bambu Lab A1. Optimize for deep bass, high sound pressure level, low activation wind speed (10–15 km/h), and stable resonance. Engineering CAD quality. Dimensionally accurate. CFD-ready internal airflow. Acoustically functional. Manufacturing-ready STL.
