Dub Bub = Double Bubbler

Version 3 is here and it surpasses its precursors in every way. Combining two 4oz mini mason jars, the Dub Bub v3 features smooth-hitting percolation and a convenient parking spot for your lighter. Its downstems and mouthpiece are both made from glass.

Rather than screwing on to the tops of the jars like v1 and v2, v3 plugs into them like a cork. The cork-component of this design is printed with TPU. Its seal with the jars is perfect. The percolators and and the bell-shaped component are printed with PETG.

There are several different brands of mini jars out there and the interior diameter of their openings vary. For that reason I have three versions of the TPU plug lid component available for download. Each has a different diameter plug. Most of the mini jars with "Spice" on the side require the 1.48" diameter plug. Most of the Ball brand mini jars require the 1.51" diameter. Of the mini jars with handles, some need the 1.48" and some need the 1.54".

All of the printed components are available here for free download. The non-printed components can be purchased at my website.

To anyone reading this- I give you full permission to print and sell this model for profit. Become a manufacturer for your local smoke shop. Sell them at the flea market, a festival, on your website- I don't care where. It's decentralized manufacturing, baby! Your 3D printer makes you money and the Hit Kit brand spreads. It's a win-win!
