Idler pulley bracket replacement for Geeetech i3 X

A replacement for the metal U-bracket with a M4 screw. The metal one already destroyed two rotational bearings by abrasion. See photo. Now the plastic pulley will wear until a stable state/position is reached. A M4 thread is included making assembly easier. Print with 100% infill for maximum strength.

_In my case (Geeetech acrylic) this is a obligatory replacement._
