This is a simple model that holds a 75mm lithophane, and clips to a generic nightlight. I found these nightlights at the grocery store, but I suspect any cheap nightlight with the same form factor will work.

This was designed based on a 75mm curved lithophane (3mm thickness) created on [https://3dp.rocks/lithophane/.](https://3dp.rocks/lithophane/.) The fit is pretty tight and secure, but I also included a couple M3 screw holes in case it needs to be clamped in.
