Prusa Plastic Z Lock

pinshape

Summary This is a straightforward solution to eliminate Z-axis nuts and concentrate lock tension at the center of bearings. Install a screw and a small nut inside the pocket, then secure your bars without worrying about nuts again. I personally encountered z-axis jamming issues prior to implementing this modification. Instructions The part is printed in ABS; simply add a screw and a nut to the pocket to securely fasten the bar in place.
