Flute mod for Irish whistle, OAK low C, but adjustable

thingiverse

I wanted an Irish flute but they tend to be expensive, so I decided to make my own using an Irish whistle. My whistle is an Oak low C, and so I adjusted this for that whistle, but you could resize it until it fits any whistle. To get a perfect fit I find that printing it very slightly too small and then softening it with a hair dryer and then sliding it over works well.
