Large Mouth Mason Jar Water Bong

cults3d

Here is a water bong that's made to work with a large mouth mason jar. This version uses a glass bowl AND a glass down stem. Opening for the glass down stem is 18mm and the length required will be decided by the height of your jar. The one pictured can use up to a 4 inch stem. A black rubber mouthpiece can also be used if so desired as seen in the picture. Prints easy with no supports but i suggest using 2mm walls to make it air tight. Enjoy!
