If I remember right, I got the handles at Lowes. They're just screwed on. I used blue painters tape, marked the holes on the tape, then put the tape on the dust cover and drilled the holes with a regular drill bit, being careful not to apply too much pressure. Take your time, and use a tiny bit to start a pilot hole first, so the larger bit doesn't slide around and scratch the acrylic when you start your final hole. Place the dust cover on it's side, keep your drill straight up and down to avoid it sliding, and drill from the inside.
