Prusa i3 Bump Stop Extender

After I had to dissemble and reassemble my Prusa i3 MK2 to repair the extruder, I found the horizontal axis endstop would not trigger because it was about half a millimeter off.

I designed and successfully tested this accessory to extend the reach by 2mm.
It attaches using the two bottom screws of the small side fan.
My original 123D Design file is included in case you want to modify it to increase the reach by more than 2mm.
