Descrição
EDIT: I slightly lengthened the whistle so that it is easier and more comfortable to whistle with.
Boost me if you like my design! Thank you!
An ultra-miniature whistle with a print time of just 3 minutes and a weight of only 0.74 grams. Despite its tiny size, it can reach up to 115 dB, making it surprisingly loud and effective. One of the smallest functional whistles possible, featuring a built-in keychain hole so it can be easily carried on keys, a backpack, or as part of everyday carry or outdoor gear.
