Here's a fun lil Lithopane , great for hanging with any light source (christmas tree lights, window, kitchen) Enjoy!

In general : 3D PRINTING SETTINGS Layer Height: 0.1mm - 0.2mm. Smaller is better for detail. Infill: 100%. You want it solid for best light diffusion. Print Speed: Slow it down, around 30-50mm/s for better detail. Nozzle Temperature: This depends on the filament. For PLA, try 200-220C. Bed Temperature: Again, depends on filament. For PLA, try 50-60C. Print Orientation: Vertical. This gives better detail and strength. Nozzle Diameter: Standard is 0.4mm on MK3S. It's fine for lithophanes.

For a 4x6 inch lithophane with a typical thickness of around 3mm, printed vertically, at a layer height of 0.1mm - 0.2mm, 100% infill, and a print speed of 30-50mm/s
