A
Pringles-can.
I use it as an airbrush cleaning station. A little modified of course.
Into the can itself I inserted a simple sponge for absorbing the color and thinner.
I made a hole in the lid, just big enough to enter the nozzle of the airbrush. On the opposite site of the lid, I made ventilation slits, taped over with a double piece of coffee filter to clean the outcoming air.
At last, the lid has to be sealed to the can by adding white glue into the gap.
Works great and saves me the 20 bucks, I would have spent on the cheapest commercial cleaning station.
Maybe some of the new brushers like to adopt the idea...
