geeetech prusa i3 z-axis wobble dampener

These clips fit snugly onto the z-axis shafts beneath the aluminum bushings, applying gentle pressure to the top z-axis lead screws that helps minimize machine vibration. They also facilitate wear-in of the z-axis lead screw brass follower nuts, effectively reducing noise levels during high-torque stepper operation in half-step mode. It's worth noting that z-wobble on early Prusa i3 models was often linked to x-axis acceleration in firmware settings, print speed oscillations, and printer construction rigidity issues.
