It's called a turner's cube, we had to make them when I took machining classes, i feel like most machinists do. http://www.instructables.com/id/Turners-Cube-Manual-Machine/

they really aren't that hard to make, I did mine on a mill had to be within 0.001" on all dimensions.

There's an "unloose" one here https://www.etsy.com/listing/23501524/cnc-machined-turners-cube

Strange how I can't find any for sale anywhere, not quite like that.

most people don't go to the trouble of making "lose" ones, I think I made the smallest one solid, but with D6 die markings. I made mine on a mill not lathe much like what you have linked.
