I also used Don Gambles clever basket mounts (Thanks Don!) for some anchor points and I used them for the Z Axis cable management.
The cable sleeve came from Amazon and it took just a little more than one package to do my machine. I ended up buying two packages.

One learning curve item about that sleeve is that in addition to needing a hot knife to seal the ends when you cut it, 500F is an appropriate temperature, and that the sleeve works better in compression than in tension so you want to cut it too long and scrunch it up (compress it) over your wire bundle and then extend it to cover the length of cable you want protected.
I often used 2 tie wraps in an x pattern to secure the cable at each end of the drag chain.
Along the way doing this process I bought a sacrificial tape measure on Amazon for ~$4 and thought it was a good deal. I later found tape measures for $1 at the dollar store and so that’s where I will buy one next time.
