My bed cable got broken after few wide prints so I designed this fix for Creality CR-10s PRO. You can see the broken bed power cable on the picture and video. The fix is done by adding chain that is changing cable angle while printing. I recommend you to print 4 "ChainUp" parts and 4 "ChainDown" parts. After printing pay attention to clear marked side surface well for smooth action.
I've added some more spacing to make post-print clearing actions less problematic. When mounting the chain please squeeze one of the part. To make it possible please print chain parts oriented as shown on the rendered images. It will improve the part's strength.
