This upgrade will move extruder motor for bowden setup from top of the frame to the x-axis. The curvature of the tube from x-axis movement will stay consistent no matter what your z-axis height is. This will reduce the flex of ptfe tube thus making filament travel more smoother.

The extruder was placed in a SnapFit Bowden Extruder Mount Anet A8 by hachiroku. I remix it and make a base so that M8 bolt can be fit on the rear of the extruder motor.
