Using blender 3d to create stl for CW pattern

[bergerud]

I am running 2.72b. It works fine in this version. The add on was actually by donation. Now I think it has become open source.

Here is a comparison I made between the Blender bas relief Vs simple z scaling. In the example, one knee was far forward. This screws up the simple scaling as, by the time the knee is lowered, the rest of the height map is over flattened. The Blender bas relief, on the other hand, flattened to the same height and retained much more detail.
