I remixed this funnel to fit down to the the labeled divided bins with 5 stalls across 2 grid squares. It sits securely in small bins and gives you a much bigger target to drop hardware into.

The wide end of the funnel has the profile of a bin's base, so it stacks or fits into a Gridfinity base plate. The ability to stack lets it double as a pour spout for 1x1 bins, which has been useful even if I'm moving things to a larger bin.

I printed it in about 10 minutes in vase mode with a .3mm layer height and .8mm extrusion width with a 0.4mm nozzle. I thought it would need a brim to stick, but it did fine without it. Be sure to set top AND BOTTOM layers to 0 so one side doesn’t get filled in.
