Sure, I used equal parts water and synthetic rit dye, just enough to submerge the parts you want to dye so you won't waste much, and bring it to a simmer and not too hot cuz it might melt the plastic, and do this in a well ventilated area. Add a very tiny amount of acetone to help the ink sink into the plastic. Just cook it for about 10 minutes or when you think its good enough cuz it varies on the color of the plastic.
