This is a model i made to be able to grind beans direct into the coffee puck before sticking it in your coffee machine. It eliminates the problem of coffee grinds statically hanging on the bottom of the grinder and has a widened lip to catch any flying coffee grounds so you can pour them back into your puck as well (the spoon shape of the base). It is designed to hold up to 22mm wide stem of the pourer that goes out the base of the coffee puck which fits most of the italian machines. (this was made for a Grimac Mia). You may need to shorten the little holder arms depending on what type you are using. Feel free to remix.
