Ender 3 Y Axis Pulley Ring Washer

thingiverse

This tiny ring was specifically designed to function as a washer for the Y-axis pulley.\r\nI had previously encountered an issue where the Y-axis belt would frequently come into contact with the wall of the pulley and become damaged.\r\nHowever, once I implemented this solution, the belt was perfectly centered within the pulley.\r\n\r\nA regular M4 washer could have been used instead, but since I didn't have one available, I created this custom ring which fits perfectly.\r\n\r\nThis custom washer is 1.3mm in height, and if it fails to center your belt correctly, simply scale the Z-axis to achieve proper alignment.
