The question is not so simple and I don't think we can answer it
without knowing how is this vertical axis related to the rest of 
the object... 

I normally mount my slides so that the near point is close to the 
stereo window, provided that the far point separation does not exceed 
a maximum value.  This rule makes sense in your case where there
is no physical infinity point in image.  I would trust and optimize
the projected appearance rather than some quantitative measurement.
