These graphics were created by converting a gray scale image into a 3D model. I found that the gray scale conversion alone produced sloping lunar phases that were distracting. I created a new model that corrected the slope to clearly show each stage of the lunar cycle. This new model works well in a large or small scale. The larger scale allows for exploration of the lunar surface texture. There are some minor distortions in the print shown below that can be resolved with some printer adjustments, but they do not distract from the tactile experience.Â
