Modification made to solve leveling problem on my 3Novatica Gate 3d. Because 3 point leveling only works with table guides in ideal parallelism which i couldn't get, so i decided to approach it from different angle. 4 point adjustment to the rescue. Project made for cnc alike machine. Laser or water jet cutter. Specification: Pictures show my plate which was based on first project. There are visible modification I've made to fit it in printer. 3D model slightly differences from pictures by half millimeter on few holes. This is it second iteration. Updated from my mistakes and miscalculations. I you happened not to trust my measurement of holes I will suggest you to take only base shape and make it done plane. Holes can be transferred from original plate. laser-cut with all holes on 3mm aluminium plate. Depends on manufacturer job files needed. It is wise to have driller with 3.0, 4.0, 5.0 and 10.0 mm drill for widening some holes.
