This task involves modeling a hammer in BRL-CAD. The hammer should be accurately modeled in such a way that it can be printed using a 3D printer.  This means that the model should have no overlaps (use rtcheck and/or g_qa gqa commands to verify) and will probably consist of two or more regions.  Create one top-level combination to group your regions.

The output of this task would be a rendered image and .g file of the model.
