For MKII Mignons with the grind dial on the left

This version is cut for the Mignon MKII series where the grind adjustment dial sits on the left side of the grinder. Check yours before ordering — the dial position changes the clearance the hopper needs, and the wrong side will not seat properly.

Across the Mignon line burr size depends on model: 50 mm on the Silenzio, Crono and Perfetto, 55 mm on the Silenzio 55, Specialita and Mignon Zero. The two are not interchangeable. What is common to all of them is a hopper sized for continuous use rather than for one dose at a time.

How it works

The bellows hopper takes the stock hopper’s place. Weigh a dose in, grind it, then press the silicone bellows so the air pushes grounds still sitting in the burr chamber and chute down into your portafilter or dosing cup instead of into your next dose.

Version 3

Every unit we ship today is Version 3. The bellows is a custom branded, factory moulded silicone part — it is no longer 3D printed, as our earlier versions were.

How it is made

• 3D printed: lid, lid lock ring, connector, air-leak prevention gasket
• Factory machine moulded: silicone bellows

Materials

• Lid, lock ring, connector: PETG hard plastic
• Air-leak prevention gasket: TPU — material info
• Bellows: factory moulded silicone

Fitting

This hopper is made for the grinder named on this page. Fit tolerances vary between units and production runs, so minor adjustment may be needed to seat it perfectly on your grinder. Every unit is covered by our 2 year warranty.
