From the blog "3D Printing in Anthropology"

Here is a tutorial for the Grayscale Model Maker in the free program Slicer, specifically for modeling pubic bones since they are used in anthropology for age and sex estimation. The Grayscale Model Maker is very quick and easy!   And I can't stand the "flashing" in the Editor.   For this example, I am using a scan from TCIA, specifically from the CT Lymph Node collection.   Slicer Functions used: Load Data/Load DICOM Volume Rendering Crop Volume
