This is a 3 piece shot glass which should be printed with 3 colors using a dual extruder. Since my replicator 2x hasnt arrived yet I cant test it myself. I will also include the full shot glass file for those wanting to print it a single color.You will need a dual extruder printer. Load all the files without moving them, they will already be arranged properly.The base will be set to the first extruder, the middle will be set to the second extruder, and the top will be set to the first extruderyour first extruder will have red filament and the second one will have blue. When the printer starts printing the middle/blue piece, pause the print and replace the red filament on the first extruder with yellow filament. Then resume the print and the top piece which was set to the first extruder will print in yellow!This is the method I intend to use to print this object and havent actually tried it. If you decide to try it please let me know if it works and post pictures! I will upload pictures myself if this works.
