20mm Calibration Cube for Dual Extrusion

This is a standard 20mm calibration cube, but with two colors so you can calibrate your dual extruder set up! In my picture you can see I printed two of them, at 90 degree angles with the colors switched. This was to check differences in x-y alignment, and test stringing since my new set up is bowden fed. That's about all there is to it. Have fun!
