Air Hose Screamer - Air Hose Whistle

A coworker gave me the idea a while back and I finally made it real.

It works, it is loud.  Use at your own discretion.  For best results try 75-90PSI, much over that it overloads the whistle and gets quieter again.

Printed at 0.25mm layer with a 0.4mm nozzle.  The round base goes down for proper print orientation.  Updated the model to reflect the correct print orientation.  Use PLA or PETG.
