Z-AXIS CTC - best of both designs

This thing was remixed with Tinkercad. Edit it online https://www.tinkercad.com/things/fQZdq2KX3qd

So I took two of the popular designs
http://www.thingiverse.com/thing:582265
and http://www.thingiverse.com/thing:496298

I combined and trimmed, I wanted to see if I could make a snap-on version that would provide benefits without unbolting anything...

Its installed, but now need to see if I can tell the difference

Use at your own risk, but if you dont like, it just pops out!
