Z-Leadscrew support (antiwobble) Anet A8

thingiverse

Another version of Z-axis lead screw support mounts with built-in M3 nut brackets for a smoother build process. This item is not intended to combat eccentric movement of the lead screws caused by misaligned couplings, but rather provides supplementary support to the lead screw itself. To achieve optimal results, all three key components - the coupling, bearing, and idler nut - must be properly aligned. In industrial design, it's standard practice to provide support to both ends of the lead screw.
