Printed fine on the A1. Small but has a mighty sound. My son loves them and is taking hand fulls to school to give away and trade for school snacks. Pretty neat little whistle. the breakaway design is good for kids.

awesome

perfect on the A1 some stringing in the mouth but doesn’t show on print and it might be a humidity Issue on my end because I never dried this filament. I rate this 5 stars. very happy

Our first quanity print on A1 worked great sons taking them to school Thank you
