This was created to display 4 lithophanes with a 2mm frame and 2mm thickness with the size being 100x100mm. pictures squared on https://squaremyimage.com/ then converted into a lithophane on https://tool.itslitho.com/CreateModel (settings shown in pictures). It is currently set up to wrap an LED strip around the middle post and the cord coming out of one of the sides. Doesn't look the best with the cord but it does its job. Separate into objects upon importing into your slicer.
