Description
The original metal cup on the Bunn G3 grinder is designed for paper bags — not for a 58mm portafilter. The result is waste, misdosing, and a workflow that never quite runs smoothly. This chute is built with a 47mm opening that fits directly onto a 58mm portafilter, so the grounds land precisely and you can drop the makeshift solutions every morning.
The difference from day one
The geometry of the original cup is simply wrong for espresso use. This replacement solves the fundamental problem: grounds go from grinder to portafilter in one direct movement — no bridging, no spillage along the edge, no stressful workarounds. If you have a stripped-down or modified Bunnzilla, a shorter shorty version is included for setups with limited clearance beneath the chute.
- 47mm inner diameter — directly compatible with a 58mm portafilter
- Replaces the original Bunn G3 metal cup
- Shorty variant included for bare/modified Bunnzilla setups
- Mounts directly on the Bunn G3 with no extra adapters
- No improvising — just mount and dose
Who this is for
It's an obvious choice for home baristas and smaller cafés using the Bunn G3 as their primary espresso grinder. If you're already running a modified Bunnzilla, the shorty version ensures clearance is never an issue. The standard version handles daily dosing straight into the portafilter without any fuss.
Delivered ready to install. You remove the original chute, fit this one, and dose. Nothing else is needed.
