Rick,
From my experience, I'm pretty sure Tom won't be able to give you an STL file. STL files are usually made using spline-based models and the model Tom is building is polygonal. Of course, I can't speak 100% for Tom, but I'm pretty sure he'll agree.
I've run into this problem with my models too. I am confident that it's only a matter of time until polygonal models can be turned into machineable files.
Tom's work is definitely on the level with some nice CAD work.
