Death whistle template

Lately I've gotten into death whistles and I've decided to make my own.

I based my design on this paper in case you want to learn more about it https://www.nature.com/articles/s44271-024-00157-7 

You will find a basic design you can print and I have included a step file of the basic design in case you are using the PrusaSlicer and want a better quallity print.

Finally, I've included a STEP file with the internal surfaces of the whistle in case you want to make your own.

In the video below you can listen to the final design as well as all iterations I went through.
