Bottle Companion

thingiverse

The companion cube doubles as a bottle opener; additionally, its Scad file enables any flat-bottomed object to become one. To use it, print, screw in an M3x25 or M3x20 cap screw into the bottom, and indulge in your preferred bottled beverage. Be mindful of potential 45-degree overhang issues; smaller layers and good fans are recommended for optimal results. And remember, if the cube starts talking, dispose of it immediately in an incinerator.
