Triple-Sided Lithophane Box

For the lithophanes, I used this website: https://tool.itslitho.com/CreateModelIn the Model tab, enable Crop and set the image size to:Width: 150.6 mmHeight: 112.6 mmIn the Frame section, leave all parameters at their default values.Make sure the Depth is set to 4 mm. I used an LED lamp kit from:https://pl.aliexpress.com/item/1005007515178736.htmlThe lamp should have a diameter of 59.5 mm.
