Anet A8 Y-Axis Part for wider Idler Pulley

This Anet A8 Frame Part for the Y-Axis Idler Pulley fits for wider idler pulleys. The gap is 0.4 mm wider than the original Anet A8 part.
Also you need to insert a M3 rectangle nut which is easier to install since the nut is not alway falling out of the frame part while installing.
Use a self-securing nut to fix the Idler Pulley to prevent self-loosening.
