I installed the aluminium extruder for my Ender 3 Pro, but it did not have a cable clip like the stock plastic extruder.
The hardware seems a little different to other aluminium extruders and couldn't find a cable holder to suit. So I whipped this one up.
It works perfectly and holds the cable at a nice distance. The cable is free to move as the X axis moves, but the cable does not fall out.
Hope others find this useful.
