Ender 5 S1 additional bed support (Updated)

This mod is still in testing.
I did not test this mod on the factory head! In the future, I will look into this and fix some parts.

I developed this mod because I started noticing Z fluctuations when the bed goes below 100mm from the print start point. I categorically did not want to use an additional Z-axis screw, and after some tests I came to the conclusion that everything would work perfectly without the additional Z-axis screw, even more, the bed began to move more smoothly after installing additional supports, the rigidity of the structure increased significantly.

I use 12mm steel cylindrical rails, I used aluminum supports for fastening to the frame, but if desired, I also modeled a printable version.
List of what you need:
-steel guides 12mm, length 450mm x2
-linear bearing LM12UU x2
-steel screw with hexagon head M4x12mm  x4
-steel screw with hexagon head M3x14mm  x4
-steel screw with hexagon head M5x15mm  x8
-steel screw with hexagon head M5x22mm  x4(When using the print support)
-T-nut for aluminum profile M5  x8
-T-nut for aluminum profile M4  x4
-nut with nylon insert M5  x4(When using the print support)

Parts are best printed in ABS, use 30-40% infill for linear bearing holders, use 100% infill for steel shaft supports.
