Made a DIY vortech cover awhile back, finally got around to writing something up about how I did it 
Anemone proof!
Product made
Supplies used: Drill, dremel, 1/8" acrylic, regular fiberglass window screen, and 3 holesaws (4", 3 1/8", 2 1/2")
Secured the acrylic to the wood so it wouldn't move while making the rings, predrilled the center 1/4" shaft for the holesaw bit
Made my disc, 4" holesaw used
Drilled again with the smaller holesaws, using the same center hole for the holesaw's bit so it was exactly centered - 2 1/2" holesaw used for the front vortech ring, 3 1/8" holesaw for the rear ring
Sanded the ring a bit, holesaw's not too smooth The front ring only needed evening out, the back ring will need to be sanded just a little bit larger than 3 1/8". A little bit of sanding and the rear ring fits snugly over the back of the vortech. Don't sand too much because its the snug fit that keeps the cover on the vortech.
