Fine adjustment ahead of manufacturing run. Tamper base plate dimension 45.8mm +-0.1mm. And fit of the funnel for minimal gap ~0.25mm.

I received the first sample from manufacturing. This first sample had more rounded edge at the base of the basket to help the material...

I took some microscope images of stamped and lasered baskets. quite interesting to see the different approaches Top row, left to right -...
