Keurig K-Carafe funnel

I use newer Keurig in Carafe mode frequently with refillable Carafe size k-cup.
But, I like to use my coffee grinder to grind the beans.
The trick is to then get the grounds into the cup.

This funnel solves that problem very well.

Just print solid with the handle down. Worked on my XYZ DaVince 1.0, so I imagine it will work with most printers.
