3018 40mm Laser mount

This is a replacement mounting to use a 40mm laser on a 3018 laser unit. It completely replaces the original mount. I also printed linear bearings to suit, therefor leaving the old mount intact for reuse. the dimensions are to suit a 8mm metric threaded bar and nut instead of the original 8mm lead screw and i omitted any backlash component as it is normally not required to move in the Z plane too often. I only move it to change focus distance for different thickness material. No special printer settings needed.
