  Sorry for the delayed email response, I'm way behind on answering
recent emails due to trying to get the new version of VMD finished up.

The safest way to get a high quality STL file out of VMD is to:
  1) download and install MSMS for your platform. MSMS is a
     solvent surface generator which VMD can use to make high quality
     surface representations, which also has the added benefit of generating
     surfaces that generally don't have self-intersections, which typically
     cause trouble with STL export and 3-D printing.
  2) load your molecule(s), set the colors and your atom selections, and
     then draw them with the MSMS representation (see commentary above)

  3) Open the File->Render menu, select "STL", and then export/render
     the scene.

You should then have an STL file which you can make 3-D models from.

Note that if you want to print a color model on one of the more advanced
3-D printers, you'll need to use VRML2 or one of the other scene description
formats, as the STL format lacks color information.
