Description
I was worried about head cable on my Elegoo 4 Neptune Plus so I made a "minimalist" L/R bumper for X-axis. It prevents the head cable from touching Z-frame harshly when X-axis homing or when printer accidentaly overshoot beyond X-axis bed dimensions.
Clearance from MIN / MAX position of my Plus (0 / 330) is still 2mm, so no problem should arise.
Print as is, then easily clip on and enjoy. Should work for any "non Pro" version of Elegoo 4. (Pro version has different rail)
Remember - everything you do is at your own risk...
Edit:added "left bumper" version, which better holds in place. Older one was sometime dragged out by cart out of its position
!!! You must change you printer.cfg in Klipper because we are moving "endstop position of X-axis" by 8mm closer to bed. "position_min" should be "-4" but it is too close to bed so filament will be spit on bed when unpaused. I chose "-6" and still have about 1mm clearance to "x home position bumper". Feel free to adjust as you wish:

position_min: -6
position_endstop: -2
