Mazzer Mini/Jolly Anti-Pop Funnel

This is my first version of an anti-popcorn funnel for the Mazzer Mini and Super Jolly. 

It goes inside the aluminium entrance tube. It's a snug fit. It prevents debris from climbing back on the ledge of the aluminium frame and it prevent a bit pop-corning by restricting the entrance diameter. 

I use it with the same bellow as the DF64 grinder or with this upside-down bean cup 

(Edit 1: Added a new V4 with tighter and higher restriction hole to have a better anti-popcorn effect, might be a bit too narrow for big cultivars like the Maragogype.)

Edit 2: Added a new V5 to replace V4 (deleted) where the under part of the restriction hole has less angle and more room. V4 was clogging with bigger beans.
