Such an engrossing thread so far, guys.  I've never done a 3d print of anything yet, and to be honest I never even considered it, but this got my wheels turning.  It's exciting to see Blender being discussed for things like this.  I did the model tutorial too, and it came out perfectly.  I might use this as my first ever 3d print too, so I'm gonna keep a close eye on the results to this thread, guys.  Keep it going, there's some good info in here.

Luxxeon, please disregard my original questions earlier.  I don't want them to detract from the progress of this thread.  I might end up having more relevant questions eventually anyway.
