Yeah, perspex is acrylic. The part is made from a ring and a disk glued together.

To machine it, I cut a square and then knocked the corners off to get an octagon. I then drilled a hole in the middle and screwed in a screw. I put the screw in the chuck of my electric hand drill and used it as a make shift lathe. Using a wood chisel I turned down the outside.

I made two disks like this. On the second one, whilst still running in the chuck, I cut near the outside edge to produce a ring. When I was almost through, I stopped the chuck and cut through the last bit with a sharp knife.

Superglue the disk and ring together and that was it. It doesn't lock in place yet (like the maxijet cover would), but I'm still prototyping at the moment.
