I apologize if my post wasn’t clearer. What was missed here is that I was pointing out the commonality between manufactures in part one of my post.
Where I think you may be confused is that in part two of my post the examples I provided were not an indication of “Same Source” but rather a comparison of “Best Deals” in my experience.

But it’s a funny coincidence that you bring this up this week. I was going to post a follow up to this thread and saw the 100+ posts and figured the post was dead or at least needed a rest. But since you asked…
I placed an order in November. I deliberately ordered two transparent PETG spools from different vendors who I strongly suspected were from the same factory. I did this precisely so that I could later share my findings with this group.
Here are the two filaments in question.

Here they are side by side in my office.
And here are the production labels and QC tags. Subsequent tests of each filament using Temp Towers, Max Flow rate and Pressure advance showed they performed identical.
I recently started to keep better records so that I could eventually maintain a database of vendors with their quality and performance. The CC3D and HZST3D have turned out to be a great PETG value from my experience.
Now I’ve been collecting similar proof from other vendors but that will take time since I am buying on price and availability so I can’t necessarily predict who will have the next sale. I am starting to archive photos of every filament I buy so that I can keep track of who’s naughty and who’s nice.
