I love board games, one in particular is Cthulhu Death May Die, which contains some 2D tokens that I have decided to bring to the 3D world, here you will find a base for the portal tokens.
*The portal base is divided in 3 parts: Base, halo and tentacles.*It does not require supports, it can be printed directly on the printing plate just as I show in one of the images.*It does not require scaling.*Once printed just glue the parts together and paint them.
