My father has a tripod adapter that he built that uses a simple parallelogram
to create a camera mounting platform that can simply be "flopped" from the
left to right position. As I recall, the resulting offset was about an inch-
and-a-half. The nice thing about the adapter is that it takes all the
guesswork (and human error) out of this process. It also reduces the time
that passes between the two photos, which can make a big difference when the
subject matter might move if you wait too long. (This is not usually a
problem with Lego models!)
I think maybe I'll try to build one of these out of Lego. It probably
wouldn't be that hard to do except for the lack of a standard tripod thread
Lego nut/bolt pair.
Aside from having the flash turned off, you probably also want to switch your
camera over to manual exposure if you can. That way, the colors in the two
images will match better than if the camera uses a different exposure for each
shot. (This is less critical than the flash thing when it comes to
stereograms, since your brain can average the colors out more easily than it
can ignore the conflicting shadow cues.)
