Summary

This can be equipped to any regular mouth mason jar. It can also be reversed for storage. The bowl joint fits regular sized bowl stems. I printed this with no supports and a .6 nozzle for a speedy print. The down stem I printed also with no supports, and a .4 nozzle to make sure the holes were good quality. The down stem fits snuggly in the hole on the bottom for a good seal. I printed both bong and down stem with 100% infill for strength. The splash guard is meant for cleaning purposes or for use if stored with water in jar. The splash guard will prevent water pouring out but does not provide a water tight seal. Splash guard version 2.0 is modified to hold stem making storage of bong less noisy and more orderly.
Enjoy!
If anyone prints this with glow in the dark filament please post a pic!

THIS IS NOT A RECOMMENDATION!!! For obvious reasons.
After having used this I noticed the smell holds in the material. I used dawn to clean residue. For smell I put 1 drop of bleach in the jar filled with warm water and let it soak overnight. The next day the smell was virtually gone.
