I’m in the process of rewiring my entire setup. I’m in the stage now where I’d like to use cable drag chain. I’ve tried a few versions out there, but none that great. Ideally I would like to print several links at once (not individually) but at the same time not break the whole thing when I try to break them in.
Anybody have a good version they swear by?
Have you looked at the tape measure trick? I’ve only been able to keep about half the links I’ve ever printed for cable chains… 
I used this one: https://www.thingiverse.com/thing:915487
Worked great.
I purchased my cable chains for X. Y and use the tape measure trick for Z. I tried printing chains and they were not smooth enough for me amazon had prices good but I found a local place that sold them. What I dont like about chains is they catch sawdust and everything on the table wants to get inside a mill you lay down the end of your Z probe Allen screws you drop and then not come back out
