Whistle with hole

UPDATE: Well, I wanted to put a little mount on it, just for fun. So now there are two different models, one with mount and one without. I have not try to print the one with the mount, but should work fine. UpdateEnd...

Just added a small hole so that you can put a paracord and have it around your neck.
Or as I did, a small paracord BOX, for the good look and fast accessibility.

NOTE: This thing is VERY loud, my ears started to ring after blowing hard and short in it. So protect your ears
