Dosing Funnel (54mm)

I designed this dosing funnel to sit perfectly on top of rim of the Breville's 54mm portafilter. With a firm push, this will sit into place and not fall off. Carefully remove the dosing funnel to release, while avoiding snapping it off and losing all of your precious coffee grinds.

Also fits under a niche zero for the option to grind directly into the portafilter.


Disregard the bad sanding in the images. I only had 800 grit paper so i couldnt get a good polished finish but its still smooth enough that the coffee grounds dont stick to it easily.

Printed with PLA+. Orientation I found worked best to preserve the seat's fitment was upside down. I suggest sanding anyway, so if you have any overhang defects on the top of the funnel, it wont matter much.
