Have a nice, refreshing IPA sitting in the fridge along with a ton of other beers that have ‘Light’ or ‘Ice’ in their name? Obviously one variety is for guests and the other is for hosts, but how do you make sure the drunkards at your house tell the difference? A beer bottle lock, of course.
Because all beer bottles are pretty much a standard size, [Jon-A-Tron] was able to create a small 3D printed device that fit over the bottle cap. The two pieces are held together with a 4-40 hex screw, and the actual lock comes from a six-pack of luggage padlocks found at the hardware store.
It’s a great device to keep the slackers away from the good stuff, and also adds a neat challenge to anyone that’s cool enough to know basic lock picking. Of course, anyone with a TSA master key can also open the beer lock, but if you’re hosting a party with guest who frequently carry master keys around with them, you’re probably having too good of a time to care.
