Do you need for somebody an original and cool gift? If so, no problem, lithophane is a cool way to make one.
The best way is to use this web page: https://3dp.rocks/lithophane/
Just set the picture to outer curved, in model settings set the thickness to 2.4 mm
Then set the correct dimensions in prusaslicer.
But if your picture doesn't fit. You can always make some changes in fusion or use the same picture as me.
I used an outdoor LED lamp, but it doesn't matter what you choose, only it should be bright enough.
Dimensions: 115×85,5mm-thickness 5,7mm
Dimensions of the space for the lamp
The assembling process is quite easy:D
