There is a new version of this thing: http://www.thingiverse.com/thing:1028274 Old one: Starting with the design from this one: http://www.thingiverse.com/thing:639951 which is a remix of this one: http://www.thingiverse.com/thing:291001 I complete reverse engineered the case and improved the cooling and some little other "bugs". The case will be attached to the upper alu profile (2020) of the base from a Kossel mini by using two M5 Screws and two T-Nuts. For cooling I will use two 40x40x10 fans. 12.09.15: Made some changes on the case itself. Just print it upright an connect the parts with M3x8 screws and the hole box with M5x8 ones to the frame.
