Cr-10 Control Box 120 mm fan bottom cover

Just another bottom cover for the control box, but instead of using all kind of feet and/or 2 powerful fans , simply turn the control box upside down and let the heat rise. From time to time it needs a little help from the 120mm fan, but for the most of the time it is almost silent (I have replaced also the two inside fans with two Nanoxia 60mm fans)
Still need to design a mod for flipping the display though.
