I saw something like this on a large online retail store and thought I could design something similar. We use them when sorting lego to pour into bags, but they could be used for nearly anything.

There is an optional insert, which can be used to stop your items from spilling out of the funnel mouth.

The tray and the insert are stackable for ease of storage.

I have also uploaded the Fusion360 file, which is parametric, so you can make them any size you want on many dimensions.

I'd love to see your makes and any feedback you may have to make it better or for future designs.
