Funnel to help transfer ground coffee into your espresso machine portafilter with less mess.
This uses the design at https://www.printables.com/model/164943-espresso-funnel-parametric , modified to fit my Breville Bambino's portafilter, which has three wings instead of two.
Prints well upside-down as recommended in original design, no supports needed.
The inside diameter here is still a little small for my tamper, but it's good enough for getting the coffee contained to the portafilter brim and removing the funnel without disturbing it.
Happy caffeinating!

Modified to fit dimensions of Breville Bambino portafilter.
Uploading partly because getting sufficient tolerance on the outside diameter to seat correctly took me a few tries! That dimension and the wing lengths could be a couple mm smaller for a tighter fit if using a more flexible filament, but this works for me using PLA+.
Cutouts for wings modified from two to three to fit Breville's design.
