Hello,

I have been using various z-axis wobble protections on my K8200, but have never really been too satisfied. I have set out to make one with in running on LMM8 linear bearings in x and y and
that in the smallest package I could think of without impairing stability and also the assembly. I
gather this will cover nicely a wobble of +/- 1.5mm in any of x and y direction.

Update: 8th July 2016

I have printed and installed this wobble remover. What a change! I should have done
this specific change with the linear bearings a long time ago. -V2 now here as I have
found some minor improvements to be made. I deem this now finished.

Update: 28th July 2016

Better is the enemy of the good. So I have a V3 which has less play in the rotation
around z by a second set of bearings. Works a little better. In addition I have
improved the design for 1mm more movement it can compensate. Last but not least I have stiffened up the sidewalls.

Update: 31st July 2016

I made a mistake with the bearing length. Sorry for that - corrected V4 here to grab!

Update 16th December 2016

V5 - I have found here and there some flaws which I have eradicated. I have updated the contraption for stability with a "bridge". The is some acetone solvent welding needed. I suggest not to use PLA for a) creep of the material under load and b) for its brittleness. I use ABS here.
