This Thing is really neat, but isn't terribly complex. It is a panel sized for my Kossel Mini using 1515 extruded aluminum. It has a cutout for a USB port (I just got a Female A to Female B adapter from Frys), a hole for the power cable to come into the bottom of the printer, and a cutout for a power switch (which I also got at Fry's). The four screw holes at the corner are spaced correctly for mounting to the extruded aluminum at the base of a Kossel Mini
