Single dosing on the Obel Junior Pro
The Obel Junior 902M is an on-demand commercial grinder built around 50 mm flat burrs, with more than 30 grind settings, a stainless steel case, a portafilter support and a 180 W motor. It weighs about 16 lb.
Obel ships it with two hoppers — a small one holding roughly 8.8 oz and a commercial one at about 1.75 lb — which tells you how the grinder is meant to be used. You pick a hopper to match your volume and then run beans through it.
Neither hopper is a single dose
Even the small one holds a dozen or so espresso doses. This bellows hopper replaces whichever you are using with one sized for exactly the beans you weighed out.
Grind, then press the silicone bellows to clear the burr chamber and chute. The portafilter support means the Junior is often used with the basket in place, which makes the between-dose carry-over land directly in your next shot — the case for clearing it after each grind is straightforward.
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.

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.
