Couch Beer Holder

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 co
