Mini Mazzer coffee grinder chute to stop all the coffee going everywhere when you flick the doser.
This is a work in progress,
I cut 1cm off the bottom of the funnel so it doesn't drag coffee off the portafilter when you pull the portafilter out.
Todo: Give the left mounting hole more horizontal tolerence - i.e. make it a bit wider (doesn't fit exactly on machine - currently some filing is needed.
