My initial thought was a screw extractor/easy out but the don't really
go small enough. The threaded part is only 5.5mm thick. The smallest
screw extractor is listed as 3mm which might well work with a hole
drilled into where the philips slots used to be.

I've never used one on plastic or the micro sizes but I've had
excellent results with standard machine screws. One end creates
something like a countersink in the damaged screw head. Then you
reverse the bit and it grabs. You do need a reversible drill motor.

It's a lot easier than drilling a pilot hole for a standard screw
extractor. They're the cat's nuts for deck screws no matter what drive
type. I've used them on damaged Torx fasteners on the bike too.

I was skeptical when I saw a set in the hardware store but I became a
true believer. Worse case you stall the drill motor or break off the
screw because they don't let go. It also avoids the trip to an EDM
shop when you break off the hardened extractor and are really screwed
so to speak.
