I couldn't find any attachment that would fit the Ender 3 V2 Neo printer, so I made this one. You can attach it to the PSU, so your cable is no longer rubbing over other parts. As PSU can get quite hot, it is recommended to print it with material that can withstand higher temperatures without deforming. I printed mine with PETG.
There are also two versions of hotbed cable strain relief covers. One have ears to guide zip tie and is easier to print, while the other got channel and is a bit easier to fit. Both versions should be printable without supports.
The author remixed this model.
This is a new part that allows to secure the hotbed chain by attaching it to PSU.
