It's a companion cube that is also a bottle opener. As a bonus, the scad file can make any flat-bottomed object into a bottle opener.
Print, screw in an M3x25 or M3x20 cap screw into the bottom. Enjoy with your favorite bottled drink. If the cube starts talking to you, stop drinking immediately and dispose of the cube in the nearest incinerator.
Note that there is a fair amount of 45-degree overhang in there, and having smaller layers should help. (Half your nozzle size or less) Good fans also help.
