This is a slide whistle that is remixed from Recorder v3 by lysithia81. It uses their whistle but a new body. Ideally it is printed in two colors, and it will need to be glued together to form two parts.
The slide should be printed on its side with a high wall count for maximum strength. No supports are necessary, but a brim may be required to keep the tube from falling over during printing.
The author remixed this model.
