I wanted to make a present for my wife and I wanted to do something with lithopanes, so here it is.

You can have up to 5 lithos on this box, or maybe use one off the sides to write a message.

Print the top frame with the 4 square holes facing up, that way there is less support and easier to take it off.

Each litho should be 100mm x 100mm, and in thickness you can go up to 5mm, but better keep it under 4.5mm, just in case. Now, the only visible part is going to be 90mm x 90mm, as there is 5mm inside the grooves on the sides, top and bottom to keep it in place.

I also added a file called litho frame, which you will only need if your lithos are 3mm or less, this way you can use this as a spacer so your lithos wont rattle in the box. Scale it on the Z axis to your needs.

Regarding the light, I used what I was able to find on my local hardware store, take in consideration that the total height of the light and the socket should not exceed 90mm, the lower the better to avoid having a hot bulb close to the the top litho. I made a hole and a channel for your wiring. You could also try a battery operated LED light and a have a cleaner look.

Hope you enjoy it.

PS. Please post pictures of your prints, I will love to see what you guys make...
