My entry for the ERRF 2021 Contest Mania, Maker Coin Challenge. Four pieces fit together to allow filament-change color changes to fully represent the EVAN Logo. Two inner pieces form the two faces of the coin. Two additional pieces screw together to contain the faces in an attractive 7-sided coin with a circular bezel surrounding the logo.
Alternative logos or designs can easily be swapped in.
