Beernacle
A small bottle opener to fit a spare 5mm bolt (commonly called a "Barnacle") on your bike. Two versions of opener accept bottles perpendicular or parallel to the mounting location. Not compatible with bottle cages, may interfere with other mounted parts, like fender stays.
I 3D printed this in PLA and, with care, it will probably open many dozens of bottles. For the ultimate in bike jewelry, get a Beernacle from Shapeways 3D printed in steel!
When you order a Beernacle from Shapeways, a small markup buys me a beer!
