This is the optimized version of MarB’s “Gridfinity Forceps Box” (great thanks for the .step file).

I added various rounded corners, made the base a bit thicker, and removed unnecessary features.
It should be able to print faster and help keep the forceps centered in each slot, and it should also be stronger enough to hold forceps with stiffer springs.

If you’re interested in similar designs, I have a dedicated YouTube video that shows them and gives an overview in a kitchen or studio:

Happy printing!
