brock x-axis cable chain for JGAurora A3S (and A5 I think)

Revised 20230220: Link tolerances refined significantly to minimize play between links. Only revised link files were updated. Original Post: I built this from scratch primarily as a learning exercise and for the sheer fun of it. Having no prior cable chain experience, I'm not entirely sure how the chain should behave, but this one seems to work remarkably well. This assembly is purely optional, but I disliked the way the x-axis motor wires rubbed against the hotbed, occasionally causing issues with the hotbed connector. The assembly positions the cable away from the hotbed and maintains control over its position at all times, preventing conflicts with the bed, bed connector, or printed parts. The assembly utilizes existing screws on the printer to secure everything in place, eliminating the need for new hardware. Initially, I struggled with printing small overhangs used on rounded edges of parts. To overcome this challenge, I added a small wedge as support, which worked effectively but required clipping off with side cutters after printing. As a result, I've included two sets of everything: one set includes the support wedges and another does not (for those who can print overhangs effortlessly). The cable retaining clip, designed to snap into place after the wire is inserted into the chain, should be easy to install and remove. However, these clips are small, so hopefully, you'll never need to take them out. If removal is necessary, use a small screwdriver or similar tool to pry underneath, and it will pop out. The JGAurora A3S uses 13 links plus the upper and lower attachments. I'm fairly certain this setup will work on the A5 as well but may require more links (17 or 18 links). It would be beneficial if someone could confirm this for me.
