The UberGB: A serious gravity bong for serious people.
This design holds 3 bowls with 18mm ground glass joints, and is meant to be epoxied or glued into the mouth of a 5 gallon water jug. A few holes in the jug and a bucket large enough to hold it, and you have the king of all gravity bongs.
I printed and tested this piece, and it works flawlessly. I'll try to upload some IRL pictures when I get the chance, but I used JB weld to secure the cone in the mouth of the jug. All that's required is the material and the will to do so.
I recommend using PETG (my choice) or ABS for the higher temperature resistance.
