That was an enlightening video. I'm amused at the spring sound as the top is removed. It sounds like "it's going to be difficult to put those springs back together!" Perhaps not. You have the advantage that you don't need the lower part and the clearance shown in the video. That means the two moving parts can be split into four and then rejoined to form something that works the same way as that shown in the video.
