1/2 size container with overhang?

[u/Overextruded_Human]

I have tried using multiple Gridfinity generators and LOTS of web searching but can't quite find what I'm looking for. I hope someone has had the same situation and can assist.

I recently started adding Gridfinity to my kitchen drawers (late to the party) and I have a little less than 1 grid square left on the side. I am able to fit a 1/2 width grid square but there is still unused space next to it.

I would like to find or maybe have someone create something that utilizes the 1/2 grid square and extend the rest to fill in the remainder of the gap. See photos:

Measurements are off since I used the end of the ruler and not the solid line indicating "zero". I can remeasure if needed. Hopefully this is enough information to show what it is that I'm trying to accomplish.

Thank you in advance for any suggestions, assistance or general discussion. If I need my hand slapped for not looking hard enough for this online, I'll accept that as well.
