Lithophane Backlight and Display

I've started converting some memorable photos to lithophanes using https://lithophanemaker.com/ and I wanted something to provide a suitable backlight for viewing.

This thing is designed to view curved lithophanes 150mm tall, 210 degrees and a diameter of 120mm. You'll need to play with photo dimensions to achieve this.

The light is provided by 6 x SK6812 driven by a Wemo D1 mini linked to ESPhome and HomeAssistant (HASS).

The image is printed in plain while PLA as is the lid, The base/back is printed in black PLA. The electronics are mounted using hot-melt glue applied to the PLA then the component pushed onto it.
