Magic Cube: bed leveling helper

Manual bed levelling with "The Magic Cube", super cheap and fun to play around with when you level your bed! Clip one end of the alligator clip cable to your heat throat, the other to one leg of the LED, when the nozzle just touches the feeler gauge it completes the circuit, thus giving you a pretty dam good constant adjustment.
