Unfortunately, the screen I used on my Mouse Rod was from K$S and is no longer sold. I had to lessen the area I planned to cover because of the unavailability.
I do have a small piece of similar PE mesh from Model Car Garage. It is 1.5" x 3" in size. Kind of expensive for such a small size, but it's of nice quality.
I also have a smaller piece of mesh done in a plastic, but don't know where that came from.
