First of all, many thanks to Camiel for this very good hardware, it is really amazing.This is a cover for both, for the great GEN6Deluxe PCB and the Arduino with Ramps 1.4 shield. Therefore the design is flexible and the LCD with knob and SD Card, as you can buy for example at reprapdiscount.com can even be mounted. Because I do not own an LCD, I take over mainly the measurements and the great idea for the reset knob from Chri, find under http://www.thingiverse.com/thing:28767.Please have a look to the assembly manual. If you encounter warping problems, use the files with the "warp preventer" and fix the edges during the print with some clamps. I have installed it and it works fine. I have silenced the fan with a resistor and the cooling is still good enough. You should try it out.
