It's an accessory to avoid fatigue in the the Two Trees Bluer bed wire connection while moving back and forth.
I printed out mine cable guide in PLA.
Please feel free to modify and send feedback.
Also, I would like to give credit to the ender 3 cable chain (Thingiverse number 2920060) which I have used as a parameter.
Cheers!
