Well scold me if you must, but I used my old blade. I searched high and low for the newer blade but couldn't find it. The old blade is a 64 tooth general purpose blade, I bet as old as the table saw (15 years probably).
I think the biggest issue I had was when I wanted to push the acrylic sheet across the saw, the saw wanted to lift the acrylic upward and this would cause a fair amount of chipping. I had to get my hands a little closer to the blade than I normally do to prevent this but I just moved slow and got it done.
Anyway, baffles are cut and siliconed in. Here's a close up of the edges. If your picky, definitely use a better blade.
