Cable Chain

This is a minor remix of RotoScan's Cable Chain that prints better on my 3D printer. I was having issues with curling on the curved overhang that would cause large print trays to fail when it caught on the print head. Also the original Chain Links would sag in long chains as there was no stop to keep the link from flexing backwards a few degrees.

I solved both of these issues with a simple change to the link. I can now print large trays of these links with no failures, and the chain remains perfectly flat over long unsupported distances as well.
