MakerFarm 5mm anti-backlash z traps

I designed this to fit the MakerFarm Prusa i3v (tested on the 8 inch) for less backlash. It's pretty much identical to Wesner's except it's made for the springs I had on hand (hence why I supplied the sketchup file) and designed for the stock 5mm rods.
Simple design, just pop an m5 nut onto the threaded rod, then the spring, then another m5 nut and screw it down to your desired length. Then slide the printed part over it and bolt it to the x axis :)
