Wolf Whistles are a small, easy and 'loud' prints. Keep one handy all year round for sports, in case of emergencies and fun for Halloween or use them as a small low cost gift.
The outer chambers are a different length from the centre chamber so, when blown hard, make different pitch 'ear piercing' sounds. Combined they make a loud dual pitch whistle... or place a finger/s over the outer or centre holes to change the pitch.
There are plenty of 'whistles on Thingiverse however the Wolf Whistle is as much about a fun way to present a whistle as it is about producing an actual 'wolf whistle' but, with a bit of practice and experimentation with finger positions, you can achieve sounds representing a Wolf Whistle
There are two different Wolf Whistle stl's provided. One is for a standard whistle and the other includes a facility to place it onto a key ring.
For additional information please refer to the images and print setting.
