I sketched this out in SketchUp today and thought I would share. I took my influences from Sal Buscema, Michael Golden and Butch Guice on the direction of the render as well as the original toy designed by Bing McCoy.

This is about 40mm wide, so one may wish to scale it down further before printing. Not sure which way to lay it for printing, as the eye slots present an overhang in all orientations except on its back.
