[VIDEO] Create Your Own Countersunk Holes In Plastic
All you need to use is a flathead screw that will be similar to the one you'll use, and a heat source, like a soldering iron preferrably.
Basically, put your screw into the hole that you want to make into a countersunk hole, and touch the soldering iron to the screw to heat it up. It will slowly melt into the plastic, laeving your screw sunk into the plastic. Check out the video for the proper guide, and hopefully this is useful to everyone!
