6-chamber whistle guaranteed +122 dB V6 DANGER!!!

This Whistle is built for one purpose: being as loud as possible. Every printed unit is guaranteed to exceed 124 dB, making it one of the loudest whistle designs you can print — well into the range where hearing protection matters. ⚠ Safety warning: Prolonged exposure to sound over 124 dB may cause permanent ear damage. This whistle is genuinely loud — please don't blow it directly next to anyone's ear, and be mindful of repeated close-range use. Key features: - Print-in-place — no assembly required, comes off the print bed fully functional.

- Guaranteed loudness — every print tested and verified to exceed 124 dB.

- Keychain-ready — integrated loop for attaching to keys, bags, or gear.

- Compact and durable — small enough for everyday carry, sturdy enough for real use.

Use cases: - Emergency and safety signaling — hiking, camping, outdoor activities where being heard from a distance matters

- Coaching, refereeing, or crowd/attention-getting situations

- Everyday carry (EDC) on a keychain or bag

Printing tips: - Print in the orientation shown in the photos for the cleanest print-in-place result with no supports needed.

- A fine layer height (0.12–0.16mm) helps the internal air channel form cleanly, improving tone consistency and maximizing volume.

- PLA works well; a slightly stiffer filament may hold tone quality longer with heavy use.

Extremely loud, genuinely functional — use responsibly, and keep it away from ears at close range.
