Hi-performance whistle

thingiverse

When using this device, exercise extreme caution! Use at your own risk. Never point the whistle in the direction of your vulnerable eardrums. Optimized for printing without supports: simply rotate the Diffusor 180 degrees and the Tripod-mount 90 degrees. Enable supports only for the resonators-mount. All other files should be printed as is. Requires an adapter to the compressor, just like in the photo. However, it can be used without a compressor due to its remarkable strength, which rivals that of powerful lungs. Usage: 1. Breathe air into the device. 2. Rotate the ring to achieve the desired frequency of sound. Adjust the frequency by moving the resonator inside the mount accurately. Remember: the resonator can be inserted from either side. The smaller the size of the resonator, the higher the sound you will produce. With some experience, you can generate piercing sounds that are extremely harsh on the ears.
