16:9 lithophane box

When I was making a gift, I came to realization that there are no 16:9 or, in other words, landscape format lithophanes available for download.

The design was influenced by this instructable:

Notice, that this design does not support rgb led strips.
Also, the hole in the center of the lid is for improved passive cooling. I know that this might have been not necessary, but given the fact, that if you enclose it, then the heat will dissipate through top and lithophanes themselves and will create a small oven inside which will lead to the melting of the glue that holds the led strip. You can read more about it here:

In other words, you don't want to make a gift, that will die within hours of usage.
