Plastic Beverage Bottle Bong

With a detachable mouthpiece, this bong is small enough to fit in a purse, fanny pack, or hollowed out book. And it's so cheap to print, it's almost disposable!

Taking the soda can bong to another container, this thing makes a bong/water pipe out of plastic beverage bottles such as 2-liter, 20 oz, and other sizes as long as they have the same kind of cap.

The bottle should only be filled so the secondary intake is above the water line for clearing smoke.

Requires that you get a bowl and downstem or make one possibly out of aluminum foil.

Print the main file with support. It screws on tight for me and actually bubbles more nicely than the soda can version. Then you can choose which mouthpiece you prefer as only one fits on at a time.
