I have tried all the coffee extractors on thingiverse. All ultimately broke except the "Yes another coffee extractor but stronger" by buzzerco. The problem was the coffee often gets stuck because of the cross beams. I added some more support and removed the middle and so far its the girlfriends favorite design. We collect the coffee grounds for our compost pile.

Uses a wide mouth mason jar as a catch basin.

Edit: v2 has a taller lip... I may go a bit taller. So far so good.
