Death Whistle is a good name. This thing sounds SOOOOOOO freaky/creepy. I printed this at 150% with .8mm walls after a failed 100% attempt. My nozzle is .4mm so I guess that was the issue. It’s like the jump-scare audio in a horror movie. So good. No post processing and just printed as-is in the stl file. One of my favorite prints for sure.
