I was looking for a better solution for removing the coffee grounds from the portafilter of my DeLonghi EC 680. Up until now I used a spoon or knocked the grounds on a kitchen towel. Both made a big mess.
With my interlocking/screw on knockbox it is just two to three raps and the grounds drop as a puck in the box and can be put into the bin or the compost. The knockbox has enough room for two pucks but i usually empty it after every load.
It might fit other portafilters from different brands but I have not tested this. This fits the 52mm inner diameter and three tabs of the portafilter of a Delonghi EC 680 perfectly.
I printed mine in TPU with a high infill, so I can rap away on my kitchen counter without worries. The prototype was PLA and it worked great as well but might break earlier.
UPDATE 01.11.2024:
Added a version without build in supports. HUGE thanks to user https://www.thingiverse.com/AndrasKovach for changing the model in Fusion and sending it to me!
