Soda can flaslights case/holster

What kind of cases do you use for your soda can flashlights? Cheap sunglasses case fit perfectly for SP36. But what for bigger lights e.g. Astrolux EC06 or Wurkkos TS32. I was looking at cases for bluetooth speakers, but they seems too big.

You could use a British Army 2 magazine pouch.

If you can fit an IFAK or WebTex Thermos in it your flashlight will fit too and they are cheap as chips.
