The file 'Safety Whistle 3D Printer Model' is (stl) file type, size is 454.0KB.
Inspired by the "Storm Whistle" I found by searching for whistles online, I created this thing.
Print the pea first
You must drop the printed pea into the whistle's circular chamber while it's printing. Wait until the whistle has printed at least 10mm high (the base thickness is 2mm, and the pea is 8mm diameter).
I printed the pea using "spiral vase" mode. If you do not have that option with your slicer/printer, print with one shell, 0% infill (no infill). That will give you a nice, light, hollow pea for the whistle chamber.
Believe it or not, it will (and needs to) print without support (the inside of the whistle needs to be hollow with no obstructions). This will test your printer's bridging capabilities. The bridging and next two layers may be a bit messy, but you should get a nice top surface.
