This is very interesting DIY matte box :-)
Very cool find. I made mine in a very similar way although I used metal for the flags . I made plastic flags but the top one would not stay flat and would sag on the ends if it was warm.
Altogether too good. Are you trying to embarrass me with this DIY?
I secretly don't want to DIM [Do It Myself]. I really want to wait for a CN (Chinese Person) to DIFM.
