What is the recommended way of cutting out a square or rectangular hole in in plastic?

Here's an easy way to make square holes with no ugly over-cut gouges:

Drill out the four corners with a round bit. (Keep the middle inside the square you want so the outside of the drill holes form the square.) Next use a dremel or saw or something to cut away the middle, joining the circles. (The cut lines are blue, the excess is red.) Last you can use a file to square off the corners. (The green chunk)

Learned that from DIY shows. Who says TV is bad for you? : P

kinda common sence lol. for smaller square holes (like for tact switches etc) simply drill a hole then carve it to shape with an xacto blade

What I did for my switch holes was take a flat edge of styrene, cut it in four pieces, and super-glue the pieces to the correct shape, then bondo it in. It works very, VERY good.

Would'nt this be more at home in Case contruction?

I'm just saying because I have been getting yelled at by mods lately for putting Stuff like Guitar hero 3 stuff on the Forum 42.

We have a Case contruction forum here.

Plastic is technical unless you want the molecular equation and Make up for it.
