This is a remix of this

I remixed the bottom to hold a 70mm push (puck) light, also remixed the top so that it is a solid panel so you can use 4 images and I left the original top panel for a 5th image, so hope this helps. I did leave the cable channel in the bottom in case you find a plug in light that will work with the base. Thank you for downloading.

Lithophane size: 130mm x 130mm x 3mm (So remember to edit your photos to square)

I have also just loaded photos in to Cura and use it as well since sometimes I get issues and Cura seems to work. Your choice use what works for you.
