54mm Coffee Guide Cone (Breville)

thingiverse

Print this the right way up with a small support to hold the outer rim. You could probably print it upside down too, but you'll need a brim. This guide is useful if you're using an external grinder to the ones that are sometimes built into coffee machines (like my Breville BES870). It captures more of the coffee grinds that would otherwise spill out as you near the top of your basket, particularly in darker, stickier roasts. Enjoy.
