Another Whistle: Simple but LOUD!!

thingiverse

First attempt at crafting a whistle, a simple yet potent design that produces an ear-piercing sound when used to maximum capacity. The loudness is so intense it makes your ears ring if you don't use caution. Print Settings: Rafts: It doesn't matter which type of raft you choose. Supports: No supports are needed for this design. Resolution: A minimum resolution of .2 will suffice. Infill: Opt for an infill setting between 10-20 percent. Notes: This whistle can be scaled up or down without losing its effectiveness, and printing it on its side is the recommended approach.
