I saw the basic "Shot Glass Ice Cube" part then immediately wondered why only one? An ice cube tray has several cups to make a bunch of ice cubes ... then I realized that sometimes the freezer gets full of stuff and a big long tray doesn't always fit ... so why not make an adjustable tray ??? So I did it like this ...

When I was young and drinking I always thought a standard "shot glass" was small ... hence these are oval so they give you a little extra fun ...

YES, that bottom design is on purpose ... so if the cups get stuck in the frost of older refrigerators you can get a fork or knife under the edge and pry it upwards ...

And yes, this is MakerBotable.
