Dosing Funnel for CoffeeJack

I bought a CoffeeJack some time ago and always had to be very careful to fill the grinded coffee into the portafilter basket.I created this funnel which makes this process a lot easier. It is big enough that the glas with coffee from the grinder fits above and its inside diameter is large enough at the bottom for it to stay on the basket while using the stamper. It also makes using a WDT easier.
