Quad Tone Air Hose Screamer - Air Hose Whistle

It works, it is loud, it is now in 4-tones at once! Use at your own discretion. Printed at 0.25mm layer with a 0.4mm nozzle. Use PETG(preferred) or PLA. Make sure you align the Z-seam along one of the valleys between the chambers. See my single tone model here .
