see what I mean. Even without the washer nipple, they would have had to modify either the washer's hole or the mounting post for it to even fit like your assembled piece does.
Look back at the pics. the recess in the base where the washer goes is shaped perfect for the funky side of the washer to sit in facing down and the flat side wouldnt work. Otherwise, they would have sculpted a flat recess for the flat washer to sit in. Then look at the movie pics. the first two shots look like it is flat, and I dont know about the third shot. must be a reflection.
furthermore, I would have faced the protruding pins down pointed at your wrist for the clear piece and not up like your assemblers did. I hate to cause problems as well, but I think they assembled it wrong.
