Mason Jar Blow Off Airlock
thingiverse
I really liked Sui Generis's Keg CO2 Purger & Blowoff Connector. It really is a great idea, but I don't always Keg all my Ciders and Mead's that I make. I bottle batches to give out as gifts and for visiting friends and family. So I wanted an easy to print blowoff type airlock for my 5 gallon buckets that I ferment in. I also didn't like printing the hose barb on its side with supports so I made it two parts, to be printed vertically and glued together. The domed vent piece can be glued in to place and is mostly there to keep debris and dust from getting into the jar.
