I have some lithophanes and wanted a cool way to put them up on a window with double sided tape. The design here will hold them up and also has a bit of a slot to keep them in place.

I used this cool website to make lithophanes in case you were wondering.

Feel free to remix if too big or not big enough for your favorite lithophane.

I printed without any supports.
