TL;DR No.
short version: No. Bad design.
longer version: Drag chains 101: defined bending radius, no overlapping cables, and strain relief on both ends. This design has none of those properties.
very long version: Read up on energy chains.
Great points. I appreciate the critique. Can you recommend a design that ameliorates the issues you mentioned?
I make my own when I need them, so I am not aware of good models for the Ender 5. With the points mentioned, I think you could tell whether a chain is good or not.
Quick search. This looks promising: https://www.thingiverse.com/thing:4635454
This is the interface/linking I use. One detail that isn't visible: the "hub" isn't a cylinder. It's a truncated cone.

Thank you so much for this. I definitely have a better idea of what to look for. I see exactly what you mean regarding the linkage. I have yet to see that system for limiting the radial movement. I love the elegant simplicity. I haven't had any problems with my current chain, but I will definitely incorporate these elements into the next chain I print.
