The first feature I will zoom in on is the cable mounts and strain relief at the steppers. @randysteck came up with an excellent original design where he attached the mount to the stepper motors with zip ties. I modified this a bit and ended up building a new design that attaches by replacing two of the original screws on the stepper motor with longer screws that are used to mount cable support. I also changed the zip tie mounting to allow the device to act as train relief and to secure the cable cover if you are using one.

Hardware:
Another feature you can see in the above photos are end caps for the steel tubing and grommets where wire passes through the tubing.
Here is an additional photo of the end caps. This isn’t as much functional but adds a finished look and keeps stuff out of the tubing.
