3D-Printed Captain Crunch Bosun Whistle

This 3D print is interesting because the original whistle is kind of infamous - John Draper (Captain Crunch) discovered that the frequency of one of the two tones was 2600hz - perfect for tricking pay phones to transition from toll free to "paid" without requiring payment. The 3D printed version probably isn't as accurate, but it makes a tone quite nicely and it's a cool artifact to add to the collection.
