The Solo DF64 grinder Cavity

The cavity fits my DF64 perfectly and feels solidly machined, no wobble or rough edges when I snapped it in. I've run maybe twenty shots through it since swapping, and the consistency is back to what I expected from the grinder.

I was a bit nervous about getting the fit right, but the cavity seated perfectly into my DF64 without any extra shimming. The internal housing feels sturdy and the grind consistency is back to what it was when the grinder was new.

Installed this replacement cavity and the alignment was spot-on—no wobble or binding issues at all. The internal housing feels solid and machined to the exact same specs as the original.
