Rancilio Rocky Grinder Bean Stir Lid

I have a Rocky Grinder I love, but I use some really oily dark-roast beans, and the beans often get caught in the throat, and I wind up sticking something in to stir the beans to knock them loose. I removed the protective guard and it worked better, but still had to mix the beans at times to get them to drop down.
