Redditor /u/the_colorist is an adherent of the Burning Man lifestyle. Every year, he attends that countercultural festival in the Black Rock Desert of Nevada.
One of his recurring problems is that the beers that he carries on his bicycle go flat as it bounces around. He needed to hold them steady, so the_colorist invented and printed this automatic stabilizer.
In the reddit thread at the Burning Man subreddit, many commenters urge him to patent the idea, as they think that it has great money-making potential. He refuses to do so, but freely gives the CAD files to anyone who wishes. As a true believer in the Burning Man lifestyle, he sees profiting from the joy he can bring his fellow festival-goers as morally indecent.

Needs to take a big swig when first opened to keep from spilling when going around corners. (Alternate comment: Who can't kill a Tecate before it goes flat?)
Abusive comment hidden.
