Experimenting with a 0.8mm nozzle on my Prusa MK3S at 0.64 layer height. Doesn't look as nice but took about 45 minutes to print!
Articulation works really well, except that some of the teeth broke when I was trying to open the jaws. The tail was pretty difficult to turn as well.
This is such an awesome design, thanks for sharing it @mcgybeer!
