This is a model directly inspired by the Michael Keaton Batman symbol as seen in the Flash movie. It is designed in two pieces with a notched backplate as well as the bat symbol with a corresponding post. The post fits into the notch and has a backstop built in to insure there is separation from the back plate.

If printed with an AMS you can paint the backplate yellow or finish both pieces and paint the old fashioned way :-). Recommend printing on a non-textured surface if you want a smooth bat symbol.
