There's plenty of various cable drag chains out there on Thingiverse but I haven't found any that allows installation without disassembly of wires.
Apart from that the chains I've seen were quite bulky.

That's why I designed my own version i Fusion 360, allowing me to customize all the features of chain link:
- height (12 mm)
- length - distance between link hinges (20 mm)
- width - outer distance between walls (20 mm)
- diameter -
