Gridfinity box for the 10 piece metric Icon reversible ratcheting wrenches and the 7 piece stubby metric pittsburgh ratcheting wrenches.
This overhangs my bed printing flat about 15mm. Had to split it as you can see in the photo. There's about 1mm of clearance in pretty much every dimension so it's pretty snug but stuff fits.
The stubby 18mm has a wide open end head and to fit in my drawer, I had to drop it down as far as I could and cut the base where it sits. But if you don't run into drawer height issues, you'll be good to go.
