2020 profile cable holder arm

I remixed the original cable holder by RTamer for my Anycubic Kossel Plus to be more sturdy and to have straight arm.

It snaps on any 2020 profile so it's definitely not just for this one printer :)


The arm can also additionally be more secured with M3 screw & t-nut if user wishes to, but this is optional. I've found this to actually not be necessary with my use case, but I included it just in case.
