litophane lamp

I have a version for curved or round lithophanes, a base suitable for a lithophanes 15cm high and a base suitable for 20cm high lithophanes. you can create the lithophane in this free site http://3dp.rocks/lithophane/
you will have to make the 4mm thick frame.
there are 2 versions of lithophane 15cm according to taste, both functional.

updating: I added a lithophane door for 20 cm lithophanes with a softer curve because I was told that it is too curved
