something I did not have access to the last time this conversation made

a tiny part, and other technologies (sintered powder or UV-cured resin)
are likely to be too brittle, especially with such fine features.
Ethan, you might try talking to Shapeways or Ponoko and having the gear
printed out of stainless steel. A very small gear shouldn't cost that
much and may last longer than a delrin part.
There's a very nice gear program here: http://woodgears.ca/gear/index.html
I own a copy and it produces excellent DXF files suitable for laser
cutting.
