Quickly fills, then levels out, measuring cups. An approximate 1 cup measure is supplied as an example, designed for this creation. Good for kernels, seeds, flour, sugar, anything in large quantities but small bits. A funnel, lock(to allow controlled flow), and the base are given. When the handle lines up with the ridge on the funnel, it is completely open. When it is perpendicular, it is fully shut. Prints in 4 parts, in 3 files, on a Replicator 5th Gen. No extra parts are required.The assembly is quite intuitive. Put the measure on the base in the slot, and put the funnel with the ingredient over the measure. The funnel should fit into the base quite snugly in the hollowed out section. There should be only a small amount of space between the measure and the funnel. Note: Though this may seem obvious, put the lock&handle in BEFORE the substance. You will have a gigantic mess otherwise. Cleanup: Wiping down the base and measure with a damp sponge should work just fine. The same goes for the funnel and lock.
