CURRENT VERSION: 

V1.8 - Design that is a lower pitch making it easier to blow through, also removes the airway splitter, the air pocket is slightly enlarged (helps with volume) - Overall louder and better

VIDEO DEMONSTRATION:

This is a comparison video showing the difference in volume - comparing this whistle and the well known and great V29 whistle https://www.printables.com/model/285368-v29-whistle.

Although this whistle is about a third of the size it still manages to pack the the same amount of punch.

PRINT SETTINGS:

Nozzle - 0.4 NOZZLE OR FINER, anything larger cannot be guaranteed to work properly!

Walls - 2-3

Infill - 10%+

IMPORTANT! - Your printer must be dialed in for the whistle to work properly. This is due to small air passageways and sharp corners which are essential parts for the whistle to work best!
