Hi everyone! This is my first attempt at a whistle so be kind! I wanted to 3D print a 2 tone whistle that had a somewhat low pitch, high volume, and a distinct ringing sound. Oh, it had to be small. Easy enough eh??I tried other whistles from other people but i was not satisfied so here I am! The whistle is light, (3.7 grams at 15%infill) and very compact (22.5 by 47mm with a thickness of 5.4mm) but very resistent. Let me know what you think about it! By the way, the 3mf file provided is the profile I used to print that, it's not optimized, but it works!
