About this 3D model
This is a two color Star Trek Discovery badge. The big part (Discovery Badge Bicolore Noir) is printed in black PLA. Obviously it needs to be printed face down. The small part (Discovery Badge Bicolore Blanc) is printed in white PLA. It doesn't really matter which side is down, but it is smoother if the front of the part is on the printer's bed. The white part snap fits inside the back of the black part. Glue may or may not be necessary.
