Unfucking Adapters

One for my fellow nerds...

In an attempt to unfuck my flat a bit, I'm trying to be tidier. What can I do with not-nicely-shaped tech stuff that I don't need out all of the time, but that I can't stick into the attic?

Thinking things like chargers that I use when travelling, cables for devices that only need charged every few weeks, spare bluetooth headphones, keyboards & phone/tablet cases.
