The diamond drag is not going to cut deep enough to give a nice bright image. On larger stuff a 90 degree vee cutter works well if you are going to try smaller stuff use a 60 degree.
I am having good success cutting 3D images. The trick is to blow air on the cutting bit at all times. This also cools the plastic. I made a blower out of some 1/4 inch steel brake line (NAPA sells it) and 3/8 inch poly flow tube from Lowes forced over it.
Clockit sells clock motors and EBay has all of the rest of the stuff you need.
