Espresso Machine Coffee Tamper

Tampers are tools used to pack (or "tamp") espresso grounds into the basket of an espresso machine. The purpose of a tamper is to pack the grounds evenly for a quality shot. Essentially, you're taking it from a loose pile of 'dosed' grounds to a tightly compressed cake inside the basket.

This thing consists of 2 parts, which are screwed one into other. So it can be used "as is" or filled up with epoxy resin, small rocks, sand, salt or any other material to make it heavy.

Initial radius is 52mm, it matches to my Saeco Poemia HD8423 espresso machine. But you can easily customize it in either Fusion360 (source included) or just by changing the dimensions in your slicer software - Simplify3D factory file is included as well.
