As background, I built a CNC machine in 2008 and have gradually taught myself the ins and outs of using it over the past several years. I've gone from simple two-dimensional projects to bas relief to full 3D. It has a cuttable area of 36" x 24" x 5" and lands squarely in the camp of hobbyist CNC. Additionally, I am well-versed in a number of graphics and 3D modeling packages. To duplicate the results here, you'd need access to a similar CNC machine and be reasonably good with 3D software tools.
The subject of this instructable is actually the result of a modeling tutorial titled 3D Modeling in Silo: The Official Guide by Antony Ward, David Randall and Nevercenter. The chapters in that book take you through a character modeling exercise in which you create this figure using a program called Silo 3D. This is exactly what I did and the outcome is a compelling blond hovering in a rocket pack with a pistol in her left hand.
It was at the end of this book that I felt I wanted something more for my efforts. I figured that buildng her as a life-size sculpture would make a kick-ass exhibit and expand my abilities along the way.
