Easy Print Whistle

thingiverse

I created this design because all the other ones I downloaded had print quality issues. I specifically designed this to have most walls at 2.4mm thickness. This way, choosing three shells with a .4mm nozzle ensures easy printing without patchy infill messes. Make sure your fan is on before reaching the top of the air outlet section for smooth prints. Be cautious when blowing out the first time - it's much louder than I anticipated and can hurt your ears if you blow full force without ear protection.
