Calibration Box of Awesome

This is a calibration box that is very useful to test things such as retraction, ooze, and bridging. Besides looking cool, this design takes up less plastic and prints faster than some similar designs because of it's reduced thickness and by shaving down unnecessary areas. This box is about 20mm tall and 30mm x 30mm long. The towers are 5mm x 5mm wide, and the bridges are 20mm long.
