About this 3D model

Inspired by Radus' part I re-did it from scratch to fit my needs. I had a pretty bad wobble on my left side from a slightly bent z threaded rod. I could also see where the nuts were wearing from being bound so tight in the x carriage and not being able to move with the bends in the rod. Here is a video that shows my rod and the wobble it has with the part installed: http://www.youtube.com/watch?v=Qlw363e1z_k This version has an opening that will fit two M5 nuts (spread apart) and then I inserted a 7mm diameter spring that pushes the two nuts apart. This basically adds anti-backlash on the nuts / z rod also.
