To add a hinge to the case, you can design it as a separate component and then attach it using screws or glue. As for making letters on top of the case, you can use 3D modeling software to create the text and then extrude it to the desired height. Make sure the text is connected to the case properly for printing. Remember to consider the size and thickness of the letters for them to be legible and printable.
