I made one for a friend. I used a 0.4mm nozzel, 0.8mm shell, 100% infill
really cool 2 tone! did you just hot switch filament in the middle of the print?
Yes. I've hacked the feeder on my Ultimaker 2 so that I can just unclip the filament drive bearing and hot swap on a pause step without using the interface. I was making this for a friend that is a big Az Wildcat fan. He loved it.
