Rostock Max v2 Wire Saver

It is a sleeve that snaps into the 1" hole where the hot end, extruder and layer fan wires go through. I couldn't get the heat shrink supplied with the kit to shrink enough so it would stay above the hole and it has since slipped down slightly. I will be adding some split loom on top of it, but I figured having a smoother edged surface can't hurt to help prolong the wire insulation from wearing.
