Cable chain buffer for 10mm threaded rod

I printed and installed cable chain on my prusa i3. The chain would sometimes flex the wrong way and catch on a linear bearing, preventing the bed from moving along the Y axis.

These C shaped clamps are attached to the 10mm threaded rod on the bottom of the machine and held in place with a zip tie. They prevent the chain from ever reaching the bearing. I needed two to make it work. You can see them in the top right of the photograph.
