PrintrBot Plus Z Screw Isolator

suffering from z axis wobble?

This mod allows the Z axis screw to wobble without influencing the position of the nozzle. The Z axis nut is captured in a bracket that is not rigidly coupled to the X end brackets as with the regular Printrbot Plus.

This was created because I was having problems with z axis wobble. I saw some one using the Prusa Z Screw Isolator (thing:20147) and decided that there needed to be an equivalent for the printrbot plus. this may also work with the Printrbot LC however i have not been able to test this (if some one has an LC feedback would be apreciated))

Update: new stl file to fix one of the parts not slicing properly.
Update: new version with parts swapped so if you suffer from retraction issues they happen on the less important side of the print.
