Coffee Bean Dosing Funnel

A funnel for pouring single serving doses of coffee beans into a vial. Traditional funnels tend to jam as the beans are asked to move past each other. This design allows the beans to move freely into the vial without getting in each other's way.

The vial ID I used is 22.0 mm. This is rendered by a program written in go so it could be re-rendered for other size vials.
