Dosing Funnel for Comandante grinders

This is one of my favorite additions to my Comandante grinder. Normally dosing funnels are used for portafilter baskets, but this one is the perfect size for the top of your grinder. It's heavy stainless steel, milled out precisely to a rim that rides confidently on your C40. It enlarges the opening just enough that you'll never spill coffee beans on the counter again. The opening of the funnel measures 2 3/4 inches, and will also sit on top of the jar to help you fill that with beans.
