This profile is the frame/lightbox I designed to fit my litho prints.It is 230x230x3 to fit Babu labs build plate of 256x256x256. I have designed this frame/lightbox to fit the litho that are in my collection. It has a pressure fitted removable back and a lip on the front to hold the litho print with just a few drops of glue. Below is the link to my LED light strips I use. I have added a small brim to the frame plate to keep the corners from lifting.
I will be adding more Lithophanes to my Makersworld profile, so click the follow button to see what I have and what's being uploaded
