Lil Bub = Little Bubbler, the mini mason jar pipe!

Rather than screwing on to the top of the jar like v1 and v2, v3 plugs into it like a cork. The cork-component of this design is made from TPU, a rubbery filament. Its seal with the jar is perfect. The other two components are PETG.

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!
