Never use a dremel on plastic unless you're intending to remove large amounts of it indiscriminately. The dremel's spin quickly heats the plastic, deforming it slightly and actually liquifying the stuff that the bit is cutting against. As it rotates, the bit wobbles around in the hole being drilled, carving a hole much wider than it would on a metal figure. You'd be better off putting a cutting bit into a pin vice and working it by hand. Slower, yes, but on small details it gives you greater control with far less potential to damage the model.
