LED Lithophane box

I have printed others lightboxes but always found the light sources expensive so after finding some cheap light sources on Amazon I built these two light boxes around them.The Light stick gives better light but was more difficult to fit in, The round one is a good fit but may not give as good a light in bright conditions.I had to put the cable at the top of the box as if I put it near the bottom the hole I would have to make to allow the USB connector to go through would allow light to shine out the back. I am working on a fix for that but in the meantime this way seems to work ok.The Lithophane size needs to be 156mm wide x 105mm high by 2.5mm thick and has a 2mm border. Please be gentle with feedback lol,, still very much a novice at this designing side of things.
