This is the version 2 of my original popular whistle. Its even louder, as if the old one wasnt loud enough.

It uses only 10 grams of filament, prints fast, and has zero overhangs - so no supports needed :-)

Two versions are available - one with a hole for a keyring, and one without.

Important notes:

• It is very loud for a whistle, and may cause temporary hearing damage at close range.
• Be mindful when using it around others and pets, especially indoors.
• requires moderate airflow to activate

Happy printing!
