Seeking cable management ideas....

Has anybody come up with an inexpensive way of organizing cables
among groups of Raspberry Pi hosts? The problem tends to be power
supplies. Most come with a fairly long cord and coiling it results
in a sort of bird's nest. Shortening it might be possible for the
older Pi's, but probably not for the later USB-C models. Stock
length cables are better a foot long than an inch short, so in the
end they're all at least a little too long. 

Adding usb-serial adapters for monitoring serial consoles, powered
usb hubs for external disks and the disks themselves makes for a
very confusing and hard-to-trace nightmare.

It's all made worse by a need to individually remove and replace
hosts and components without disturbing others. For example, when
testing suspect components. More than once I've unplugged the wrong
Pi to hard reset a stalled host.
 
There's a very old photo at http://www.zefox.net/~fbsd/pi_cluster.
Now the tangle has grown to seven Pi's plus a few hubs and drives.
The network cables were re-routed but USB and power remain a mess.
I'm working on a cleanup while waiting for the new Pi5 to arrive,
but progress isn't impressive.

Has anybody come up with a way to make the excess cable "dissapear"
while preserving the ability to change connections?

Thanks for reading, and any ideas....
