Step-by-Step Guide: Creating a Custom Coiled USB C Cable

Custom coiled USB C cables are not only functional but also add a unique aesthetic to your mechanical keyboard setup. Making your own coiled cable allows you to tailor it to your preferences in terms of color, length, and style. In this step-by-step guide, we’ll walk you through the process of creating your very own custom coiled USB C cable.

Materials Needed

Before you begin, gather the following materials:

  • USB C cable
  • Paracord or nylon sleeving
  • Heat shrink tubing (various sizes and colors)
  • Soldering iron and solder
  • Heat gun or hairdryer
  • Wire strippers
  • Coiling rod (such as a pen or pencil)

Prepare the Cable

Start by cutting your USB C cable to the desired length using wire strippers. If your cable has a detachable end, remove it to make the coiling process easier.

Coil the Cable

Wrap the exposed wires around a coiling rod, such as a pen or pencil, to create tight coils along the length of the cable. Keep the coils even and consistent for a professional-looking finish.

Secure the Coils

Once you’ve created the coils, use electrical tape to secure them in place. Wrap the tape tightly around the coils, ensuring that they remain in position.

Slide on the Sleeving

Slide the paracord or nylon sleeving over the coiled cable, starting from one end and working your way to the other. This will not only protect the cable but also give it a sleek, finished look.

Solder the Connections

If your cable has a detachable end, solder the wires back onto the connector, ensuring the correct polarity. Use a soldering iron and solder to make secure connections, and cover them with heat shrink tubing for added protection.

Apply Heat Shrink Tubing

Cut the heat shrink tubing into small pieces and slide them over the exposed wires and connections. Use a heat gun or hairdryer to shrink the tubing, applying heat evenly to ensure a tight seal.

Test the Cable

Before using your custom coiled USB C cable, test it to ensure that the connections are secure and that there are no shorts or breaks in the wiring. Plug the cable into your keyboard and computer and check for proper functionality.


Creating your own custom coiled USB C cable is a rewarding DIY project that allows you to personalize your mechanical keyboard setup. By following these step-by-step instructions and using the right materials, you can craft a cable that not only looks great but also performs reliably. So gather your tools, unleash your creativity, and enjoy the satisfaction of using a custom-made cable for your keyboard!
