Hello. I really wanted to add some cable chains to my shapeoko to clean up the wires but I needed an easy way to connect it to the axis. I saw other people connecting the chain to the motor but I wanted to make use of existing holes in the frame. I made these two parts which allow the chain to connect to the shapeoko. I included a picture of how I connected it on mine.

Here is a link to the cable chain I used (Thanks for this upload!):
