This is a remix of the left side of Z braces for Ender 3 by ProperPrinting. I had some issues on the extruder side with the original ones since after a certain height the threaded bar was clashing with the filament, especially in my case since I am using a filament guide.
For this reason I designed one with a certain offset and a different angle. Additionally I added a slot for a 608 bearing in which you can center the Z axis in order to keep it perfectly parallel to the rail.
Hope you find it useful and big thumbs up to the creator of the original one, ProperPrinting, for his amazing content. Amazing job dude!
