If you have a laser cutter or CNC machine you probably have a Cable Carrier Chain (or want one). They are quite expensive but with this DIY Laser Cut Cable Carrier Chain project you can simply make your own if you have a laser cutter. Martin Raynsford wanted to add one to his laser machine but didn’t have the time to wait for one to be mailed. You can find the svg file on his site so you can now also make your own.
