So, after a bit of testing, I came up with this small whistle, perfect as a hoodiebead. It is quite loud (90 db in fact), so it can help you to call for help in emergency situations. But it also serves as just a fun toy to take with you.

I also included a 3mf file for fuzzy one, just as an experiment. It doesn't lose any of the original sound, so if you like textured models, you can download that. But I'm afraid it only works in PrusaSlicer.

Print settings:

I'd recommed you to use the 3mf file, where are painted the correct positions of the seam.

• 0,2 mm layer height
• 2 walls
• If you don't use the 3mf, do this with the seam painter:

• other settings are optional.

Sound test:

Feel free to remix! I included .blend file to make it easier for you.

Hope you like my design and have fun!
