I don't have a place to put a can of beer or soda when I'm sitting in the corner of my sectional couch, so I made this thing which keeps a can upright.

The center hole diameter is 68mm, which will hold your usual 2.6" / 66mm diameter north american beer can. It also holds a 64mm diameter north american beer bottle with a little bit of slop, but it'll keep a bottle upright.

OpenSCAD file is attached and customization is enabled, so you can easily customize the model to suit the beverage container sizes in other parts of the world, maybe even modify it into something a bit better looking :)

Enjoy!
