If You are like me and bought a mr coffee espresso maker you know it does not fit to common esspresso equipment. I am working on a set of tools for mine. First is tampers, with the taper inside the filter one size does not work for 2 cup and 4 cup. I have a 51mm tamper for the 4 cup, but for the 2 cup it needs to be a bit smaller ~97-96%. The second part is a tamping station still in the works.
