Summary

WARNING: Made for tobacco use

This is a waterpipe. I finally did some hallowing to do the airflow where as the others were cut out through different connecting shapes. I formed this one with the shell tool.

Print in non-toxic material.

Note: The clearance for the bowl piece is just under 30mm but with a 74mm shaft bowl piece or any conical bowl piece the clearance would be no problem. With my bowl pieces, download the 74mm model for glass, metal, (or combustion resistant plastic.)

WARNING: Nylon printing for anything combustion has a risk of toxic shock syndrome.
