Dolce Gusto pod opener v0.5

Aluminium sheet of a Dolce Gusto coffee pod (capsule) can be opened with a paper knife or a kitchen knife, but I don't like to use them as the sheet is wet inside, but not food.
Neither do I want to throw away wet and dry wastes (coffee grounds, plastic, aluminium) together.

These are the reasons why I designed the pod opener. You can open the pod easily with this gadget with fun:D

PLEASE NOTE:
In a Dolce Gusto coffee pod, there are inner films (in the middle and at the bottom), so I am going to upgrade this opener by adding a stackable ring(s) to open them as well. In this way, this Thing is a Work-In-Progress.
