O- Whistle with LOOP

O-Whistle with LOOPAS REQUESTED - I printed these with glow filament :-) I would like to introduce you to my new O-Whistle with LOOP.I have tried to construct a whistle that produces 2 different sounds, and here it is, the O-Whistle with LOOP.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.
