I use a large drill bit to get it started then cut it with the Dremel. Too hard to do it with a plasic cutter. I found a thin engraving tool for the dremel and at high speed it cut through acrylic like butter (because of the friction and heat), it should work the same for plexiglass.

A dremel on moderate speed is probably the best way to go. Use one of those thin wood cutting bits. Start out with a drill to make a pilot hole, and then use the dremel. Some type of metal template makes it easy to get a perfect square.
