This is a simple whistle that I designed in google sketchup, then used a ruby script to convert it to an .stl file. Hope it works! Please show me how it worked out for you: I don't have a 3d printer. This is for the cupcake cnc contest. Whistle 2 is a better version. it should be larger. Like, one inch by one inch by two inches.
