Having tried to do this, I can confirm that the cut edges (which took forever) were browned and nasty.

Filing out a big rectangular hole in plastic is always slow with poor results. I did this in about 30 minutes on a little Proxxon mill. First time I ever used it so I was probably slow. I thought about going back and cleaning it up a bit, but decided the first rough cut was good enough.

Have you tried a nibbler? Or if you want to be cheap a nibbler attachment to a drill.

Like this one? (MF-70/CNC = MF 70 + steppers)  :o :o :o
excellent result, as far as I could see.
It took me a lot longer with the files for wood.
