Why print the whole knock box, while you can just turn your Weck jar into one?
This snaps on top of a Weck jar and allows you to knock the used portafilter full of coffee grounds directly into it.
Print instructions
I've used PET-G, 0.2mm layer height.
Most of the parts that will receive the knock were printed with 4 perimeters, 10 top and bottom layers and 50% infill. The top part of the lid is printed with 2 perimeters and 30% infill to reduce the filament usage.
Supports are needed as the bar should be rather printed horizontally for increased strength
