The filling hole of our coffee maker is kind of poorly designed for my gross motor skills so I needed a funnel to prevent coffee beans from spreading everywhere - esp. into the hinge chambers causing a major malfunction of the lid.
This is my first attempt and it fits and works really well.
We own a Nivona 788 - this funnel might fit on similar machines as well.
I'd highly appreciate any comment and please post a picture in case you actually printed one of my designs. Thank you!
