The Ultimate DF64 Anti Popcorn Funnel

thingiverse

Provides protection against popcorning and, by extending the funnel, allows for all the beans to sit inside the funnel. With shorter anti-popcorn funnels, some beans sit on the bellows and have to be manually pushed down. If you are also using the 10 degree base, beans will get stuck on the shallow angles of both the stock bean hopper and the shallow angles of shorter anti-popcorn funnels. This funnel eliminates the problem. I like to remove the entire bellows to load beans because I do not like to faff around with the metal cap. It is quicker and easier to remove the bellows, rubber and all, to load the grinder. As such, this funnel uses an interference fit to stay in place for easy one-handed removal of the bellows. The funnel needs to be pushed into place and essentially becomes part of the grinder. It does not require much force and is removable, but it doesn't just set in the stock bean hopper either.
