Hi Jeffrey, you can try buy an A4 opaque acetate sheet (of scaled thickness), I guess you can find these even in stationaries, and a rod of brass (donno thickness from the top of my head), both shouldn't cost much though.
Then take a surgical knife or some other cutting tool, and start cutting thin strips from the acetate sheet to make the vent flaps. Once you have cut enough of these strip, prepare a drill the size of the rod (or slightly thinner), and drill holes in the strips to accomodate the rod, or else keep a candle near you, and heat a rod to melt a hole or two in each strip, then cut the required rod lenghts, and start inserting the strips one by one and gluing slightly to keep position.
It may sould a rough way, but I think its an economic way of doing such a thing.
