I used both the remade top link and remade bottom link. My printer is fairly new and came with the cable strain relief pre-installed so I had to remove that completely. Wrapping some gaffer's tape around the cable before zip tying it into place makes for a tighter fit and probably better strain relief.
I never printed the original top and bottom links, but the remade ones are very very tight fitting. I broke one link during the install and had to print another. If there's a trick to getting these to install easily, I wish I had known about it. The chain itself took about 45 minutes to install in place over the cable. On the bright side, these are so tight fitting and sturdy that I doubt the chain will fall apart during printing.
If I were to do this again, before assembly I would probably sand down the thin flat surface on each link where they touch, especially that curve that leads into a 45 degree notch. They'd probably glide a little more smoothly that way. Currently they seem to catch a bit, but not enough to jam up the bed movement or anything.

I printed all 16 links at the same time (8x top, 8x bottom), broke one bottom link during the install and had to reprint. With the links, reprint, and the cable strain relief all combined, this print probably took around 11.5 hours. The y-z vertical combo bracket was already printed for the z axis chain, so I don't count that as part of this print.
