Hi-performance whistle

When using be careful! Use only at your own risk.

Do not aim the whistle in the direction of your ears.

Optimised for printing without supports: rotate Diffusor at 180* and Tripod-mount at 90*. Enable supports for resonators-mount only. Other files should be printed as-is.

Requires an adapter to the compressor, as in the photo. However, it can be used without a compressor due to the strength of the lungs.

Usage:

1. Blow air into the device.
2. Rotating the ring, to achieve the desired frequency of sound. Moving the resonator inside the mount - adjust the frequency of the sound accurately. I pay attention: the resonator can be inserted a reverse side. The smaller the size of the resonator, the higher the sound.

With some experience, you can achieve piercing sounds that are very hard on the ears.
