This is a 2 tone safety whistle I designed to have a slight, two tone sound. Although I designed this from scratch, the basic shape and size is based off of another two-tube design (credit given in the remix section).
This can be scaled up or down pretty well.
Please post your comments and makes.
This takes 24 minutes to print on my printer. It does not need supports or rafts. This should be an easy print and easy to remove from the build plate.
