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
