This is my recreation of a $100,000 Casino Gaming Chip from the 007 movie Casino Royale for the 0.2mm nozzle contest. I know it's not an exact replica, I took some artistic liberties. It is the actual diameter of a casino chip, but only 1mm thick to shave like 7 hours off your print time lol. Some of the lines are only 0.1mm wide. I recommend you have your filament dialed in and use a smooth plate. Happy Printing!
