Prusa Z Rod Constraint

Description
A small modification of ScribbleJ's excellent Z Rod Constraint which adds a flat surface to mount a mechanical switch endstop.
I didn't have enough room for both a Z Rod Constraint and an endstop holder on the bottom of my left Z-Rod, so I combined them.
Update: I printed it out and it didn't quite fit, so I extended the endstop holder. Also, I added the sketchup files as requested.

Instructions
Your mechanical switch endstop will need to be glued onto the flat face of the modified part.
A 608 bearing will need to be placed into the middle of the part and bolted onto the bottom/top of the z-rod with an M4 bolt, nut, and washer.

Can you share the OpenScad or SketchUp file? I need the same thing with just a tweek or 2.
Done. I also made some big changes because it wouldn't fit at first.
