I used the original cable holder for quite a long time because I had some connection issues. There was only one issue with it. In combination with the LED-strip for lighting I installed I could only drive the printing head to a z-height of 180 mm. So I made this flatter version. With this one I gain extra 10 mm compared to the original version and still have no connection problems.

I made another version of the cable holder. I removed the bed leveling sensor some time ago, because I addes an Ultrabase to my printer which the sensor cannot detect. This opened up a new cable path. With this flatter installation I can use the complete z height again.
