Model Overview & Print Notes
The survival whistle is very loud, around 116 dB. It's easy and fast to print: 21 minutes with 0.2 mm layers or 15 minutes with 0.3 mm layers, and it weighs less than 4 grams. If you need a good whistle and a quick print, this is your model: super easy to use and extremely loud for its size of 42 x 20 x 7 mm. I used a free web calculator (https://whistlemaker.com/calculator/).
No supports needed, I use 15% infill.
Thanks!
