The measurements were taken from two different sources. When I gathered
the data from both sources, there were slight discrepancies, so I took
an average of the two to derive a standard set. The first source
is the official saber in the Star Wars visual dictionary. Knowing
in advance that the activation box was two inches, I was easily able to
determine the remainder of each component by scaling the entire saber based
on the two inch activation box. The second set of measurements came
from a well crafted replica.
