I would like to start this post by saying that acrylic is not meant to be drilled or cut with a saw. It is possible, but it is a fool's task.

Enough background.
Hole locations were marked on an acrylic sheet by placing the layout drawing on top and tapping down with a scratch awl to make a small dent in the surface. Border width along the edges and between the modules was measured as the width of electrical tape. In the future, the tape could be applied, even color-coded, to differentiate the different portions of the device.
Marking holes with a scratch awl

Pilot holes and full-size holes were drilled into the acrylic sheet. Drilling had to be done slowly so the brittle plastic would not crack and shatter. Going slowly produced dust rather than chips and made a mess in the office. On top of that, the swarf was statically charged, so it stuck to surfaces and flew everywhere.
Drilling holes in the acrylic sheet

After the holes were drilled, the sheet was scored and snapped to get rid of the unneeded plastic. This was the most significant advantage of acrylic since it breaks cleanly. Even then, one edge did not snap along the scored notch.
Problem with acrylic

Despite drilling carefully, the holes were prone to flaking at the edges. Perhaps it would have been better to heat the drill bit with a torch and melt through the plastic rather than drilling holes. It was a mess. Don't try drilling acrylic.
