Lithophane Test Cards are designed to help users determine the optimal print settings for 3D printed lithophanes. Variables such as filament color, opacity, slicer settings and lighting display conditions can have a dramatic effect on the appearance of the final image. The Lithophane Test Cards allows users to dial in an appropriate lithophane model height to reliably achieve the desired contrast under the final lighting setup.
Test cards are included at 3mm, 5mm or 10mm test heights. These test card can be scaled in the z-axis before slicing to fine tune the settings.
These Lithophane Test Cards were created using the Test Card image at https://commons.wikimedia.org/wiki/File:Test_card.png and converted into an STL via the awesome http://3dp.rocks/lithophane/ by @MarkDurbin104
