One of my hobbies is working with SMD electronic parts, which are very small and easy to lose. To organize them, I use some plastic storage boxes that are designed for diamond art painting and always remind me on TicTac containers. The only problem is that the openings of the compartments are quite narrow, so I made this funnel to help me pour the parts in. I guess these little funnels can be useful and handy for everybody that works with these tiny storage boxes.

The dimensions of the openings may vary slightly depending on the brand of the storage box, so I chose a funnel size that is not too snug.
