The Problem: The weight of the Z-Axis Bed/weight constantly presses down on the lead screws, compressing the Z-stepper motor bearings. Combined with lead screw whip, this causes horizontal "Z-banding" artifacts on prints and faulty motors.
The Solution: A thrust bearing is placed in a printed housing on top of the stepper motor. The lead screw rests perfectly on this bearing instead of bottoming out on the stepper motor shaft, completely isolating the motor from the downward load.
My build: The parts are the original Voron Z_Motor mounts, on a 2.5mm steel plate and a 24.05mm hole (horizontal expansion must be tuned propertly).
Material. Print them in ABS only.
