This simple stand holds lithophanes that are 80mm.(lithophanes are 3d printed etching that reveal a picture when you shine light through them). Note that the lithophane will only fit if it's 3mm thick or less. The hole in the back should hold most tea light candles. I would recommend using LED candles as real candles will melt your lithophane. I uploaded a .3mf file and an .stl file for which ever you prefer as well as a .f3d file to make it easier in case you want to edit it in fusion 360. Prints without supports, brims or rafts. I printed mine on 0.2 mm resolution but it doesn't really matter. I also printed mine with 10% infill but you could probably do it with less.
