business card - lithophane

An idea for another type of business card with a feature of lithophane. I designed this in Design spark Mechanical 5.0. I used the common values for the card. Only the thickness is a bit more because I needed the height for colour changing. I don't have MMU. I set the brightness of my picture a bit higher and after that, I cut the picture and I used a lithophane tool to convert it into an STL. Later I added some letters and a frame. It was a bit tricky with a 0.4 mm nozzle to print the small details of the small letters.
