All of the handhelds will have respective cases for sale. You can also choose to download the 3D Printer file for that cases. When picking a case, you would choose the color, and for an extra charge, you can add an image to the back of the case. This image will not be an option for the 3D printer. The case is designed to help protect your devices from bumps, and drops. It does not protect from water damage though. Cases do not work with the other accessories such as the clock dock, or phone dock. You would need to remove the case to plug such device in.
