It seems that the funnel outlet was not strong enough and broke under very little use. This was beefed up and in the process had the internal material removed, which make more sense for a number of reasons. There was a constriction made through poor design and the material was reduced significantly.

Some observations from the use, about one hour, is the amount of dirt on the outlet of the cyclonic separation section. Knowing that this system will not remove all the dirt particulate from the air it still seems like a lot. There seems to be a small amount of fluff catching on the inherent print imperfections that might be seen in the images below. However, it also might mean that a Hepa filter that all systems like this run is clearly needed.
