Mini Strong Whistle

A compact yet extremely powerful whistle designed to be carried on a keychain. Despite its small size, it produces a very loud and sharp sound. With a print time of about 10 minutes and a weight of only 3.3 grams, it is easy to print and carry anywhere.   Ideal as a safety, outdoor, or emergency signaling tool. Due to its high volume, use with caution – prolonged or close-range blowing can cause ringing in the ears or discomfort.
