Anet A8 E3D V6 XL mount

I noticed that the carriage of the x axis has some tolerance if you try to turn it clockwise or counterclockwise.
After a long search, I unfortunately had to realize that none of the e3d carriage designer has solved this problem.
So I chose a template https://www.thingiverse.com/thing:2099577 that seemed useful to me and reworked it a bit.
First, I placed the two upper sliding bearings with a distance of 43mm to each other which has significantly improved the print quality at higher speeds. T
