Bed cable chain for Tronxy XY-2 Pro

thingiverse

I have grabbed the original thing (https://www.thingiverse.com/thing:4713226, that is not reachable somehow presently), got printed and installed. However, I've found it too weak soon: the both base parts - enclosure end and bed end were bending even with steady bed. So, I've redesigned these two parts from scratch, keeping only chain connectors original. The chain link with lock, natuarally, left untouched. At the same time, I've designed the enclosure end as double-purpose part: it is the basement for the chain and - at the same time - is the enclosed guide for Z-motor's cable. This part is quite high, but not too much - the clearance under the bed level nut is big enough, I did have no touches so far. The bed end part made more strong (maybe even too much) and is double-purpose also: it includes upper stabilizing bushing for rear left bed spring (I use these bushings: https://www.thingiverse.com/thing:4088681). Bed heater cable did need extending to let the chain run smoothly. The original thing's autor wrote he usees 15 links in chain, but I use only 14 with my length of cable. You will need check yourself. Good luck.
