Pictured is the short version, Ill publish the cable clips on another post if interested.

The author remixed this model.
Ive cut and adjusted the positions to better fit a BMG flipped the right way up instead of the backwards orientation that Anycubic has it. You will need to reverse the direction of your stepper motor.
Use m4 nuts between the stepper and extruder as spacers if you need a little bit of adjustment.
