How to Make Your Own Custom Coiled USB C Cable

Custom coiled USB cables have become increasingly popular among mechanical keyboard enthusiasts for their aesthetic appeal and functionality. Whether you’re looking to match your keyboard’s theme or add a personalized touch to your setup, making your own coiled USB C cable can be a rewarding DIY project. In this guide, we’ll walk you through the steps to create your very own custom coiled USB C cable.

Materials Needed

Before you begin, gather the following materials:

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

Step-by-Step Instructions

Prepare the Cable

Start by cutting your USB C cable to the desired length. Use wire strippers to expose the wires inside the cable, being careful not to damage them. 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.

Add 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.


Making your own custom coiled USB C cable is a fun and rewarding DIY project that allows you to personalize your keyboard setup to your liking. By following these step-by-step instructions and gathering the necessary materials, you can create a unique and stylish cable that adds flair to your mechanical keyboard. So roll up your sleeves, grab your tools, and get ready to coil your way to keyboard perfection!
