crtouch spacer

Have you been messing around with your hot end, and find that you need to move your CR-touch probe a bit closer to the bed? No? Well, I guess it's just me then. Still, this matches the top of the cr-touch sensor body and is 1mm thick, so you can tweak that z-offset without having to cobble together a spacer out of junk or try to stack washers on top.
