Loudest Emergency Whistle by ThreeD-Michael | Download free STL model | Printables.com

is the best I’ve found. They’ve been tested on canyoneering trips — we use whistles to communicate over the sound of waterfalls; nothing else is piercing enough to cut through the thunder. These work as well as the gold standard Fox 40 Classic. I print it florescent orange PLA, with an 0.6mm nozzle and 0.3mm layer height, and make lanyards out of orange paracord.
