Bottom line for anyone who cares:
There is no single, or multi-factored, test for paraphernalia. The test I gave you is broad for a reason. A "connection" between weed and your vaporizer is anything a jury thinks it is. Any one of the factors listed in your chosen statute can be dispositive and the hook the jury can convict on. There is no need to meet more than one of the elements in that or any statute defining paraphernalia. They are all broad on purpose.
The test YOU gave? It has been my point from the first. But, on the above, I agree. It's what I've been saying from the start and tried to prove up with statues and cases. I'm glad you came around.
Now, knowing we completely agree on this point, reread all my posts and find out where you disagree.
(I say you, because I have many instances I disagree with what you wrote and could point them out, but, that is not the point of the thread.)
