DS4 Modular Dpad

It really is hard to improve the dpad on a ds4, the only real modification here is the addition of snap faces. Keeping with the low profile and smooth edge design of the original dpad, I incorporated some a snap system to mount faces to the top of the dpad. Most prominent is the fps stick which creates a faster and smoother transition for the left thumb from stick to pad. By also adding a post the dpad feel becomes more akin to moving the thumbstick. The second addition is a disk to eliminate the any catches when the thumb glides across the tactile buttons of the dpad.
