A male, planar head. The set includes an STL file prepared for 3D printing. It is approved for printing by Netfabb. It also includes a ZTL file with all shapes organized as independent subtools. Feel free to use it as a base mesh for further sculpting.This started as a simple anatomy exercise, where I wanted to simplify a human face. Soon I realized, that having all main anatomy features as diffrent subtools, that I can modify independently, is an incredibly nice starting point for sculpting portraits. It helps with keeping track of all main shapes. The flow of intersecting shapes introduces an engineering quality to the sculpt. I have found it hugely helpful. Hope You will too! Feel free to ask me any questions about the model You might have.
