I found this Pyrex medical beaker (flask?) at a surplus store for $2. The OD of the opening is 57mm and fits perfectly into the throat of my Compak K6 without reaching the top of the burrs. It holds 1/2lb of beans with some room to spare. Filling is like changing the bottle on the water cooler. Dishwasher safe of course.
