The Holy Screamer

One day, I got obsessed with whistles. I had already downloaded a couple of designs over the years and did like them, but I wanted to know how they worked. So I brought them into my modeler program and cut them apart, learned how they work, and set out to break records if I could and eardrums at least. I made a LOT of variants and settled on this one as my favorite. Respect it, though - it is LOUD especially when printed around at a scale of about two inches length give or take. It's brutal. Size determines frequency, of course, and they can pretty easily go from huge at around 2KHz or less (SO LOUD) to tiny at 1" and more or less 15KHz. The little opening in the front end allows them to emit without a lot of force so you can at least moderate the sound pressure, thank God, but if you really gotta hit it for emergencies, probably cover your ears for safety. I'm not kidding. My personal copy, scaled for about 2.5KHz, makes my ears ring like hell afterward, makes me feel half deaf. They WILL damage your hearing if you keep at it at full force. Just letting you know in advance.

BUT, ideal for emergency use. No, this doesn't have a lanyard hole. I could be coerced to make a version that does if people want it bad enough. This was intended to be printed with the mouthpiece flat to the bed, so it's standing straight up. As long as your printer is well tuned, it should work fine like that. I like PETG for these especially but ABS also works great. Haven't tried TPU but I don't see why it couldn't work, and even though generally these are strong little bois, TPU ought to be indestructable. Or nylon, but that seems a bit much, lol. Anyway, enjoy, and feel free to comment away or ask me whatever about em. Good luck, and stay safe!
