Surface Design (Debossed/Engraved): * All of the following art must be engraved (debossed/low relief) onto the front face of the disc. * Upper Text Circle: Engrave the text "IGREJA EVANGÉLICA" in capital letters, following the curvature of the top border. * Lower Text Circle: Engrave the text "União graça e vida" in lowercase letters, following the curvature of the bottom border. * Central Image: In the center of the keychain, engrave a stylized image consisting of an open book viewed from the front, with a flame rising from the center of the book. Style and Finish: * The model must be a single, solid piece (monolithic). * The 3D mesh must be watertight, with no holes, to ensure it is 3D printable. * Material: solid matte gray plastic appearance. *
