Creality Ender-4 heatbed holder strengthening

This part was designed to decrease heatbed vibrations by the means of increasing the overall torsion strenght of the bed holder. The z-axis space will not be decreased, since it just wraps around the bearings.
The part is placed over the z-axis bearings and screwed in place with the bearing screws. The z-axis space will not be decreased, since it just wraps around the bearings. The parts are interconnected via m5 srew. At bearing side you can insert m5 scres and tighten them against the z axis
