Here are the links to the larger version of the photos (except the last one which is not really in focus).

(edit...larger photos now in original post above.)

The filter can itself has sides that slide together and if you get one side off the rest will come apart easily.  I set the can on the side of the bench and used a hammer to tap one of the sides to slide it off.  It bent the side a little but was easily tapped back in place.
