Plexi is a pain in the ass.

Drill VERY SLOWLY. Low speed and no pressure. A small stream of water
helps; it cools the cutting edge.

De-stress the holes afterwards with a bevel and sandpaper on
a nail.

There's better plastics to sue. If it's just a flat sheet, I find
lexan types much more forgiving. It's hard to bend though.
