Cranking out a massive 135 dB , this is officially the loudest whistle design you will find on MakerWorld.

Print Settings & Tips

- Print in Place: No supports needed, no assembly required! - Layer Height: 0.2mm works perfectly. - Infill: 100% (Solid infill ensures maximum acoustic resonance and a louder blast). - Perimeters/Walls: Use at least 3-4 walls to make sure the internal chambers are completely airtight.   Warning: Seriously, protect your ears when testing this indoors! 135 decibels is louder than a jet take-off or a live rock concert.
