Z axis anti wobble #2 for Geetech Prusa i3 X (27mm rod sep.)

It is not the arc-reactor but only a printer improvement. Use this thing if you have loose z-nuts. This thing reduces the z-wobble. It does not eliminate it fully. (I'm still investigating the reason for my remaining wobble). Typical anti z wobble gliding discs (http://www.thingiverse.com/thing:1190400) are a good thing if your nut has no play.

Three versions included: (8mm smooth rod and 27mm rod separation.)
- For 8mm threaded
- For TR8x1.5 threaded. Outer diameter of 22mm.
- vB: For TR8
