Espresso Coffee Tamper

This is a simple model I created to fill a personal need. I got gifted an old espresso machine from a friend, but had no way to tamp down my coffee, so I designed a simple coffee tamper which has been serving me very well.

The diameter of the tamper is designed for 52mm to 53mm portafilter baskets, but would still work on slightly larger baskets. The exact diameter of the tamper is 51.90mm.
