Còi hình "núi đôi" (Titty Whistle)

After seeing several genital whistles, but not any titty ones. I thought i would be fun to make one, and Claptomancys model seemed perfect for a remix.
Print with your preferred settings. The model displayed in the pictures, is the first print i did of the model, with whatever filament that was on the printer and a layer height of 0.2 and it worked fine. The whistle is not loud, but it works :)
