Mendel 90 lead screw z-Axis upgrade TR8 4 hole

I took chrisqwerty's design and changed the 3 holes for 4 holes. After printing these out, I discovered that the x-end-clamps were 2mm too long ... so I've modified and uploaded those too.

*** THIS DESIGN IS FOR 8MM RODS ***

UPDATED
I have updated the models as I found the screw holes for the brass nut (z-axis) were too big for an M3 bolt, also the holes for the brass nut were too small and drilling them out ruined the part.
