I just started building my own cable chain for my Ender 3 V2, but almost every second chain broke, maybe caused by a not so good filament.
So I reinforced the walls a bit and added 1mm and also adjusted the other parts accordingly to keep it fitting. The holes and the lugs are in the same places so it should fit on top of the bases as well.
The cover has also been adjusted so that it closes cleanly.
This is my first remix, I hope you like it.

There is a litte model error which will be shown in your slicer, but this does not make any differnce, you can print it straight forward.
