Prusa I3 x endstop - wide version

My original end stop was too close to the x rods after changing my x carriage.
I created this new one which clips onto 8mm x rods. Has a long slot so the microswitch can be moved up and down for fine adjustment - a hole allows a screw to gently hold the microswitch.
Also included a slot to pass the wires through so it can be assembled and disassembled with no desoldering. Actual distance from x bars to microswitch is now 30mm.
