Working Whistle

thingiverse

I designed this whistle based on a whistle cross-section that I've printed myself and it actually works. Be aware that the smaller you print it, the more ear-piercing the sound will be, but if you print it too big, it probably won't function at all. Hopefully, you'll enjoy using it!
