This is remake of the double fan case for the K8200 i made here: http://www.thingiverse.com/thing:284410 Again this is based on the original control board cover found here: http://www.thingiverse.com/thing:168769 In this version i have opted for a much more open design allowing excellent airflow as well as the ability to check the temperatures of the stepper motor piggy back board heatsinks without having to remove the case cover. In my opinion it is also much more aesthetically pleasing. It has mounts for two 40mm fans and increased wiring room at the top and base of the case and uses the original designs base plate for mounting the control board (like the original remake made by me)Print the original board cover base, mount control board to it. Print the new double fan case and screw it to the base plate. Mount two 40mm fans. Unlike the previous version I made with good cable management you can easily fit the two 40mm fans on the inside of the case as shown in the photograph shown above.
