This contribution contains the 3D model of an endocranial cast analyzed in “A 10 ka intentionally deformed human skull from Northeast Asia”. There are many studies on the morphological characteristics of intentional cranial deformation (ICD), but few related 3D models were published. Here, we present the surface model of an intentionally deformed 10 ka human cranium for further research on ICD practice. The 3D model of the endocranial cast of this ICD cranium was discovered near Harbin City, Province Heilongjiang, Northeast China. The fossil preserved only the frontal, parietal, and occipital bones. To complete the endocast model of the specimen, we printed a 3D model and used modeling clay to reconstruct the missing part based on the general form of the modern human endocast morphology.
