Bộ chuyển đổi (adapter) cho phễu lọc cà phê OXO

I use, and really like, the OXO Brew Single Serve Pour-Over Coffee Maker (https://www.amazon.com/OXO-Single-Coffee-Dripper-Auto-Drip/dp/B01ENK41Q6).  It’s the only dripper solution that's got a reservoir tank and doesn't require you to stand there and babysit little dribbles of hot water over the grounds.  Some manufactures claim that manually dribbling water into their dripper is therapeutic.  Nonsense.  I've got better things to do with my time.  I also added a GoldTone 4 Cup No.2 Cone Permanent Coffee Filter 4" Diameter, 3.25" Height (https://www.amazon.com/dp/B0F5X266JV/ref=sspa_dk_detail_1?psc=1&pd_rd_i=B0F5X266JV) to avoid having to buy and use paper filters.  (We compost the coffee grounds, which are a lot easier to recover from the permanent filter than from paper.)

THE PROBLEM is that with the permanent filter the reservoir tank no longer sits flat on the funnel cup.  This model fixes that problem by providing a spacer/adapter between the funnel cup and reservoir tank. 

NOTE:  I see several models with printed parts in contact with the coffee.  Bad idea, I'm told, since printed parts are somewhat porous and cannot be safely cleaned.  Just say no.

Print with the top side down.  No supports needed.  I use PTEG.

Happy dripping, and enjoy!

Fusion 360 model included.
