Whistle

3D printed whistle. A total of 2.5 inches in length, .5 inches in height, and 1.25 inches in width. On the inside, it is 2 mm thick featuring a chamber to send the air flow to either the left or the right. The air then continues down the whistle until it reaches the opening of 60 degrees located on the top of the whistle. Any air that doesn't initially go through this opening, will be cycled around and pushed back up into the opening. The decibel reading is approximately 126-128dB.
