This bracket is designed to hold the stepper motor + damper and accommodate non adjustable pulleys.
It only fits the Ender 3 Pro with a 4040 center extrusion.
This bracket is needed because some Ender 3 Printers are shipped with pressed pulleys on the stepper motors. Those pressed on pulleys can't be adjusted along the shaft of the motor. Spacing the motor the depth of the damper is the next best thing.
All original hardware is used.
This is not a Remix, but I did use the bracket made by KrisHo1 as reference. So my thanks go out to them.
I found that the model made by KrisHo1 would flex when I tensioned the belt. That would cause the belt to no longer track straight, and would rub into the pulley and Aluminium extrusion. This new box frame design aids to prevent the bracket from bending under tension.
