This is a modular bong. A series of different parts, you can create an individual bong for yourself. The height of this modification is 350mm.

There is an opportunity to change a glass cup of different diameters and a regular smoking hood.

I would like to warn you that it is better to use a separate glass joint, contact between plastic and flame is not permissible! And contact of hot air and plastic is also undesirable! Use food grade plastic for printing.

There is also an adapter for a 110 mm glass dowel. and 140 mm. Under the shaft diameter of 14.5 mm.

All good and positive, use it correctly))
