Growler Saver
thingiverse
Growlers are awesome, and one of the best things about them is that instead of recycling beer cans or bottles, you can take your growler to your favorite brew pub and get it refilled over and over again. I'm not saying that recycling bottles or cans is bad, but bypassing the whole recycling thing altogether is even better. Besides, fresh beer on tap is always better than canned or bottled. I am fortunate to live near several craft breweries, so I always keep a couple of empty growlers in the car in case I have the opportunity to stop by and get them filled with an interesting and/or delicious brew. The problem is that over time, bouncing around in the car can cause the ceramic to chip the glass, causing it not to seal anymore. At that point, you have to buy a whole new growler, which defeats the point and costs money. If you close the cap, it won't chip but will shorten the life of the seal, and if there's any moisture trapped inside, critters will likely grow and spoil your delicious beverage. This is a vented protective cap designed to extend the life of your growlers. It's not necessary, but it would probably be appropriate to print this in beer filament if you have it.
