This is usually described as a 'snake' or a 'multicore' or 'loom'.  It is hard to find one that does just the three cables for 4CM but you can buy specialist products (like these http://www.pedalsnake.com/) that allow you to build your own.

For me:  I just have four quality cables (three regular and one Midi for amp control) bound together using velcro cable ties on a regular basis.  Some people use quality braided wrap around the cables.
