clamp style x end stop for 10mm rails on 50mm centers

I upgraded to 10mm rails and a quick fit x carraige so i needed to save as much room as i could. i designed this Clamp style mechanical end stop holder to do that. the holes for the switch are 9mm On center and accept a M2.5 screw..
NOTE:
these will not work with 8 mm rods they will never clamp on.
