Lid with a slot - Graef CM 702

This a lit for the powder box that comes with the Graef CM 702. It has a slit for the powder outlet, so one can grind the coffee into the box without the electro static spilling of the poweder.

This is version 1.0 and it has a few illimeters of tolerance: the slit could be narrower and shorter, the lit doesn't fit as tight on the eight-shaped powder box as the original.
