Mr.White - The bong and gravity bong combo

This crazy contraption came to be with me finding an unused "trash" piece of acrylic pipe at my old workplace and me wanting to make a portable version of a gravity bong for my friends who enjoy those.

Well this bitch can do both ! gravity AND regular.

By unscrewing the top mouthpiece you will find a hole for a bowl. Then just screw both of the bottom holes tight( or just hold your thumb on the lower one if you dont wanna print 2 caps) fill up with water, insert your bowl, light it up and release the water (better from the lower hole)

The setup to use as a bong is shown in the pictures and gifs.
In the section view of the model you can see ive modeled an extra plug for the bottom screw, Thats just if you have problems with leaking or just wanna use that only to stop the water when using in gravity mode.

Both connections for bowl pieces are 18mm in diameter, and can be used with most glass bowls. Or you can use the bowl file ive provided but please use a brass endcap inside of it (like you can see on my other designs)

I reccommend filling it up just a little over the inside dome when using as a bong.

The name "Mr.White" for the bong came to mind cause i decided to print it in the colours of the Finnish flag. White PLA with blue TPU accents (also just cause i had those in hand). And also it just looked like a science experiment (thinking of Walter White).

The diameter of the acrylic pipe should be maximum of 80mm on the outside and a minimum of 72.5 on the inside, anything in between works with some glue/sealant and the lenght is your choice.

If any questions come to mind, i will happily answer them.

infill is your choice but use at least 2 perimeters on all sides.
Support is required for some parts like the main bottom part, but only on the outside.
