Had to print this for a buddy, and thought it'd be nice to print the lines rather than try to draw them. The black lines are pretty thin so I suggest a 0.2mm nozzle, and you may want to use thinner lines than I did in the profile so the eyes and mouth come out a little bit cleaner. It may work with a 0.4mm nozzle if you set outer walls to the minimum at ~0.24mm.
