This is a whistle that actually makes the familiar whistle sound. No more air whooshing noise, but rather a concise loud sound.
I created this whistle after i discovered all the other whistles on thingiverse were not very good at whistling. I use it at my lifeguarding job everyday, and it has yet to disappoint me.
UPDATE 9/20/14 - I have tried to repair the stl file with no success using netfab and mesh mixer. I have now added the sketch up file so maybe someone else could give it a shot.
UPDATE 9/22/14 - Thanks to Dman12 the .stl file is now fixed! Thanks so much!
