Very simple tamper base station for the 49mm & 51mm naked-portafilter for Olympia Cremina and La Pavoni. It has just enough height to clear the portafilter handle from the ground and keeps it level even when not filled.
Now parametric FreeCAD 1.0 file attached.
Printed in PLA with default settings for testing.
