Loudest Whistle

thingiverse

This is a Three-Chamber Dual-Tone Whistle. It Blows Extremely Loud and Gets Louder Still When You Blow Harder on It. I Created It as a Replacement for a Friend Who Needed a High-Pitched 3D Printed Whistle Comparable to His Current One Used for Refereeing. If You Appreciate This Whistle, Consider Making a Donation! Update: I've Added a Non-Handle Version with a Loop. Update 2: I've Included an Easier Printing Version Plus a Mouth Grip. Update 3: I've Released the V3 Version, Which Allows for Upside-Down Printing Rather Than Side to Side.
