Greenstuff roller,

Instructions:

Mix your greenstuff or epoxy and leave it to cure for a few minutes so it's not sticky any more, wet your plates and roll it out into a worm with the flat side of the top then flip the top over.

Turn it so the ridges are at a right angle use the raised edge as a guide gently roll the top back and forth till you get your segmented cable.

Fee free to remix i have included the blender files so you can make different textures etc.
