open cable chain lock
thingiverse
I really loved the chain here (https://www.thingiverse.com/thing:1760952), but for a drag chain, it should only flex in one direction and click into place in the other. So I remixed the lock so that it would prevent the chain from bending backwards. I also created a smaller lock, which you can simply slide into position from the side, but then it will bend in both directions again, of course. Update 05-01-2018: - I made a different version of the big lock, which clips on more easily, but not sure how happy I am with it. You can try it out and if you have recommendations write me a comment. - I made mounts for my Anet A8 (https://www.thingiverse.com/thing:2746790).
