⚠️ WARNING: EXTREMELY LOUD.
To prevent permanent hearing damage, please use proper hearing protection (earplugs) when testing or blowing this whistle.
A sleek, minimalist single-chamber whistle engineered for maximum portability. Barely 30mm long and 6mm thick. Don't let the tiny size fool you; its highly optimized internal airpath delivers a sharp, reliable +120dB alert tone on demand.

Print & Calibration Notes: Because of the microscopic internal geometry, these whistles require perfectly calibrated filament for precise accuracy. I achieved optimal results using manually calibrated SUNLU High Speed PLA+ 2.0, printed with a 0.4mm nozzle, 0.4mm line width, and a 0.1mm layer height.
