Lithophane Light Box Slide-In Model

I designed this model to meet a need for a lithophane light box that would allow for the lithophane to easily slide into and out of the frame. I recommend using a small, flat border on your lithophanes to allow them to slide in and out more smoothly, as well as to keep from covering up any of the image. This model does not have supports, which must be added. I believe normal auto-supports work, though you must be careful when removing them. Feel free to rescale and adjust the model as needed to work meet your needs. Please note that the box will not appear to be hollow until you have sliced the file.
