/diy/ - Do It Yourself

I am running a dozen DuPont cables between anArduino and a sensor I'm flying on a drone. What woule be the best way to bundle these cables together that would be lightweight and still maintain flexibility? The sensor will be on a gimbal, so whatever I use to bundle the wires can't be too rigid, but the wires need to be well-protected enough that they can potentially touch damp grass upon landing.
