Press to tamp coffee in portafilter (with spouts or naked).
With changeable tamper sizes (mount with thin wood screw). Choose one with best fit or create own (cylinder with 9mm thickness and inner diameter of portafilter basket).
Base was designed for my Gaggia 58mm naked portafilter, so maybe will not fit perfectly bigger ones.
Mount with M5x50mm screws.
