The file 'Adjustable Palm Tamper For Breville/Sage Barista 3D Printer Model' is (stl) file type, size is 24.9KB.
53.3mm tamper for a Breville/Sage Barista Express/Pro machine.
Should fit nicely into the portafilter.
To adjust the tamping height for a higher/lower dosage just attach/detach the rings around the tamper. In my opinion this is easier to adjust than a screwing mechanism
