Anti-backlash Z-Axis nut trap

This anti-backlash z axis nut trap replaced the wooden nut traps that are used for the z axis of the MakerFarm Prusa i3v. I had a lot of trouble with my z axis where one of the nuts would walk out of the wooden nut trap causing my machine to go out of calibration. Once I replaced this part my z-axis homing and positioning has become extremely reliable.

This design is for a M5 nut that comes with the Prusa i3v.
