I recently made my first lithophane in Hueforge and wanted a case for it so I can gift it as a nightlight to my neice.
This case holds any lithophane measuring 2mm thick by 80mm wide by 104mm tall. I recommend adding a 2mm border around the image in Hueforge to better sit inside the case. Bend the lithophane to slide it down into the frame and secure it by sliding the top piece over it.
