These boxes have rounded insides and finger recess, and we use them for cutlery in our kitchen drawers. They are for Alexandre Chappel's 55mm grid system (see https://www.alch.shop/shop/assortment). 

I use these to store cutlery and other items in our kitchen drawers. This not only saves spaces, but it also makes it very easy to have the items in their own place, and easy to find/retrieve/store again after you're done using it.

This should print easily in PLA, 0.20mm layer height, 15% infill.
