Multi-material Bernie 2020 pin!
The pin backing is a separate part that can be deleted if you choose to print it as a card or enlarged placard.
Update: Oof.
Any blue, white, red, and (optionally, for the Outline part) gold filament works greats. The filaments I used are,
Blue: ERYONE Sparkly Galaxy Glitter Blue (Amazon)
White: Yousu Silk PLA Pearlescent (Amazon)
Red: Polyalchemy Ruby Red (Polyalchemy)
Gold: Polyalchemy Gold Rush (Polyalchemy)
