3:1 heatshrink, All what you need to achieve a perfect finish for your Custom Keyboard Cable !

Heatshrink tubing is the plastic sheath that is wrapped around connectors to secure them to the end of the cable, their shrink ratios are 3:1. Choose the heatshrink tubing to make it stand out and accent your (cable, keycaps, mousepad, setup.) Choose the color of your choice !


– Only the ”Red” and ”Green” colors are in 9.7mm and therefore by default they do not pass on USB A, please use flat pliers to spread the ends slightly on each side of the heatshrink.


To go further into customization, maybe you will like the GX12 connector ? If not, find all my other Diy Parts.



Why choose “Cables Hero” ?


As a custom keyboard enthusiast, i’ve always been interested in custom cables. I’m fascinated by the fact that you can match your cable to your keyboard, keyset, deskmat and other setup items. I’ve always been meticulous and since the custom mechanical keyboard hobby has become my biggest passion these past years, my goal is to provide you the best in terms of cable finishing.

(Wouldn’t it be sad to have a good mechanical keyboard but having a cheap custom cable ?) 👀
