I believe this is the version of my ABS pipe cable carrier that I ended up cutting and using for the small CNC I built in 2010. I started off my design with the link length being 2.5" to 3" long and ended up shortening them to this 2" size after cutting several of the larger links. This shorter link has nearly a closed bottom when the links are extended and the relief on the top side allows them to pivot to a fairly sharp angle. Each link has a male and female end and they snap together for easy assembly or addition of more lengths etc. They have served us well on the small CNC router/mill I made and I think this is a cheap alternative to buying ready made carriers if you have the time to make your own. For some this will not be the best alternative and they may opt to simply purchase manufactured carriers instead, but for the person wanting a real cable carrier and willing to do the work they will work very well and at an economical price. I believe when I made my first tests the ABS black pipe I got from Lowes was only $3.96 for an 8' or 10' length. I have drawn a quick sketch for an alternative design that can be made with only hand tools and a saw for the persons that don't yet have the CNC capabilities and you should be able to find those plans in the DIY Cable Management group here. If there are any questions about how to set this up for cutting on your machine be sure to send me a message or email and I will offer the method I used to cut them or try to help if I can.
