I would like to introduce you to my new O-Whistle.
I have tried to construct a whistle that produces 2 different sounds, and here it is, the O-Whistle.
If you blow in moderately, the sound reminds me of a train whistle. if you blow in with force, the whistle is so loud and shrill that it is extreme. without covering your ears, it is very painful. please use with caution.
The whistle has a pleasant size of 68mm x 20mm x 18mm and fits in every pocket, due to the closed open shape, you can put it on a keychain or pull a small rope through it to attach it to a backpack or similar.
It is EXTREMELY loud! Be careful :-)
Please print the whistle with the specified print profile so that you get a good result. A layer height of less than 0.2mm is not recommended.
Have fun with it
