Mazzer mod no.4 - the inverted cup

I have already sold my Mazzer but delivery is to take place more than a week from now (as per the buyer's request). However, since I had been planning on doing this mod for some time and I had everything I needed to do it - why not do it then? So, here we go...

When grinding, some of the ground coffee exiting the chute lands on top of the centre section of the dosing mechanism. It does not all come off no matter how many times you pull on the doser lever. You will have to brush it off and this is the most time consuming part of cleaning the Mazzer's doser. It therefore makes sense to do something about it, especially when the grinder is used in a home environment and mostly for grinding per shot.

Perhaps the most difficult part of the modification for me was to find the right vessel. I eventually found a plastic glass that I sawed off at the point where its circumference more or less matched that of the centre section of the Mazzer's dosing mechanism. I then marked the spots where the dosing vanes are located and filed down the notches to make the "chopped" glass fit snugly on top of the grinder's centre section.


The end result does not look too obtrusive. It would look even better had I been able to find a sufficiently thick clear plastic glass (making it almost unnoticeable) or a silver/stainless coloured one to match the rest of the grinder. Regardless, the effect of the mod is as desired - now (with the sweep mod also in place) the only area to clean after each session is just a quick brush of the chute. This certainly makes life easier and also results in less wasted coffee! As with the other mods, this one is extremely easy to reverse - just take off the inverted cup.
