It is best to use transparent filament, if possible, to make it look similar to the movie prop but you can use whatever you wish . It requires 8 different types of filament. Plate one has a layer change with transparent filament on the bottom and yellow transparent filament on top. Plate 2 is a combination of yellow base/red top to create an orange appearance. But again, use whatever you wish. The ball bearings should be printed at the highest possible resolution (I did 0.12) otherwise they will look pretty ugly. Good luck and may the Schwartz be with you!
