Christmas tree bauble lithophane to use the light set of your Christmas tree to diplay the shadows and let the light flow trough the thin parts of the model. 

As it is a lithophane, it will be hard on retraction and need clean dry filament for better results. Red silk PLA on the pictures.

Print at 0,1mm detail profile in prusaslicer or lower for better results. 

Use in and out brim of 5mm for better bed adhesion.

Thin walls and thin attachement on top, dont be afraid to drill a small hole at the top for better attachment if broken. REV2 design has the strongest attachment on top
