Improved MK3S X_End_Idler

thingiverse

This is a beefier X end idler designed for the MK3S and potentially other printer models as well. It boasts thicker side walls that shield the screw from coming loose at its point of entry under the screw head, thereby preventing it from pulling through with ease. Three M3 hex nuts are reusable or can be obtained from your spares kit; simply press the idler into position before securing it tightly in place. Once properly tightened, it will not rub against the sides unless over-tightened.
