Lithophane Test Card

pinshape

Lithophane Test Cards are designed to help users determine the optimal print settings for 3D printed lithophanes. Factors such as filament color, opacity, slicer settings and display conditions can dramatically impact the appearance of the final image. The Lithophane Test Cards enable users to fine-tune their models' height to achieve the desired contrast under specific lighting setups. Test cards are included at various heights: 3mm, 5mm or 10mm. These test cards can be scaled along the z-axis before slicing to further adjust settings. These Lithophane Test Cards were created using a standard test card image from https://commons.wikimedia.org/wiki/File:Test_card.png and converted into an STL file via the website http://3dp.rocks/lithophane/, courtesy of @MarkDurbin104.
