When I bought my aeropress, it came with this weird hexagon thingy:
What is it for?
It took me an embarrassingly long time to realize the purpose of this hexagon shaped funnel, so I am sharing this via a self posted answer.
The hexagon funnel has three purposes:
It is a funnel to make it easier to pour your ground coffee into the aeropress opening.
It is a funnel for cups with a small opening at the top. The image shows a shot-glass as an example. Trying to use an aeropress with a cup that is too small sucks.
It is a stand, so when your aeropress is stowed, it all neatly stacks together.
