Anti Wobble for K8200

This is a design for reducing the wobble of the Z-spindle for the K8200 printer, this design uses 6 mm steel pins. Drill the holes in the part so it moves easy, also add some lubrication. My intention was to use LM3UU bearings and a 3 mm dowel pin but this worked soo good that I never bother to change it.
