Human Head

This afternoon I did a tutorial in Blender on modeling a base-mesh for a human head.  The head can be used for the sculpting tools in Blender.  The 3D file came out good but my printer, Ultimaker original, had trouble with the more flat parts of the model.  As you can see in the pictures.  The part of the chin has gone wrong. That is a limitation in the printer. Or I should add some support items.  Maybe next time.
