Endstop Holder for Z-axis / fixed mouting

It's only an adapted holder for the endstop of the Z-axis. I use the great adjustable Z-EndStop-XMotor.stl of enrico_19 (thanks a lot for this idea!) to switch.

For the lower bracket it was hard for my little printer to put another adjustable part. Now these two things are like a fixed and a loose bearing.
