Ultra Compact Mini Whistle 115db

heavily inspired by Franken3D Ultra Compact Mini Whistle. Unfortunately remixes are not allowed, so I reworked it a bit.
 

I have uploaded additional different lengths to create different tones, the standard length is 20mm.

The given length refers to the interior not to the total length of the model.

Apple Watch measures 115db!

I recommend printing as many pipes as you can get in your mouth!
