Ultimate Triller Whistle with 3 Tones – loud, louder, loudest! 📢🔊

Seeking an exceptionally powerful triller whistle that stands out from the crowd? Then this ball-less 3-chamber whistle is perfect for you! Thanks to the ingenious design by whistleblower on Thingiverse, it offers three distinct tones that combine into a bone-jarring signal – ideal for sports, the outdoors, safety, and anything requiring you to demand attention (ear protection recommended! 😉).

✅ Maximum volume – Perfect for emergencies, referees, or your next hike.
✅ Ball-less design – No wear, no malfunctions, always reliable.
✅ Print-friendly – Printable without supports! The eyelet shows slight visual imperfections, but functionality is not affected.
✅ Tested & proven best – I've printed many whistles, but this one surpasses them all!

Should the eyelet quality bother many, I'm considering uploading another print profile with supports. Let me know!

Have fun printing and whistling! 🎶😃
