Update - 4/4/15 I have uploaded the new Little Mermaid pendant. I changed it so that lights are light and darks are dark. I also manually edited the picture for the lithophane to have enough contrast to carry through the details I wanted to show. This took a few iterations of editing, processing and printing. I think that it turned out great! My camera did not capture it very well though. I also decimated the image some so that it is easier to process for printing. There was much more detail there than was needed for this scale.

Update - My daughter wore this to school the other day and when she came home, she asked if I could make a pendant for other princesses. When I said I could, she pulled out a handwritten list of all the girls in her class with the princesses and colors that each girl wants for their pendants. I had to laugh.

So, now I have created one for Cinderella and am working on one for Belle. While working on test printing them, I realized that I have the polarity backwards on this one (lights are dark and darks are light) I also found that I could get better detail if I opened up the picture first and edited it some to create the definition needed for this small detail level. I will be posting an updated Little Mermaid later this week and others will follow and I will provide more detail on the steps I took to make them in case others want to try.

End of update.

My daughter wanted me to make her a Little Mermaid necklace, so I thought I would try making a tiny lithophane pendant.

I used MakeALot's lithophane generator to create the lithophane: http://3dp.rocks/lithophane/

Then I imported it into Tinkercad to cut out the circle, put a round rim on it and a loop for hanging it. I also created some custom support to help hold it upright for printing.

See the instructions for tips on printing.
