The Creality CR10 Extension Cables are a great way to gain more options for organization and cable management in your shop. It can be difficult to find a place for your control box that doesn't get in the way of the printer or other items on your bench, while still allowing the bed cable to have enough slack. These extension cables add a significant amount of extra length to your existing cable sets to allow more flexibility in control box storage. No need to open the control box up - these plug in between your existing cables and motors.
