I read the thread by Lanx, but I can't type using the ms ergo 4000, since the hand angle is too diagonal(Have one at home, tried typing on it and failed miserably.) I might try to make it backlighted green, and add a green plate to it. However, I'm still stuck on the designing, and slightly procrastinating with it since I still don't have enough money for it yet. My concern is that the 3-D printing material might cost a lot, and the design may be slightly off(eg. USB wire is in a wrong place).
