I reinforced the bearing housing and moved it lower to capture the rod across the full height of the bearing.

I reinforced the bearing housing and moved it lower to catch the rod with the entire height of the bearing. I left a safe distance from the screws on the table, as you can see in the 4th photo.
I also enlarged the holes for the square nuts so that you can print without internal support.
Before assembly, I threaded the middle hole. I also washed the bearing in IPA and lubricated it with Prusa grease.
Due to its high strength and resistance, I printed it from ASA filament.
Remember that in addition to the three upper screws, there is a fourth one, which you tighten after removing the rear cable cover. The two screws that secure it are located inside, on the rear wall of the chamber, right behind the z-axis screw.
The support works as expected, eliminating any potential vibrations. It does not make any noise, which is important at the high speeds of this crazy printer.
Update 10/06/25 - I have improved the bearing position for people who sometimes have trouble leveling the bed.
