I've been working with a lot of M3 screws lately for SOME REASON and I have been wanting a cleaner solution for accessing and returning screws from smaller gridfinity bins. The other gridfinity funnel trays I found were not exactly what I was looking for, so I made my own! 

This tray features a funnel on one corner that indexes nicely with 1 unit gridfinity bins. It is just high enough to stack with when it contains M3 screws, and pairs nicely with this tray I made using a Gridfinity Stackable Modular Baseplate, and a custom handle I designed, to bring my bins from my storage area to my workbench.
