thingiverse
I designed this to keep dirt and pocket lint out of my inhaler, which can spoil your day (or worse). I modified this from another thing (https://www.thingiverse.com/thing:2428140) and made it shorter. If you print it in white it might look like a storm trooper, ok maybe not....
I had good results printing it upside down with the concave portion up.
