FFPU - IKEA 4x4 shelving unit (Brookland DC)

Might be 3x3 but pretty sure it’s 4x4. It’s white - the link below is the shape/size/instructions for reconstructing it. I have many but not all of the dowels/screws needed; I have enough that it shouldn’t be hard to find substitutes at a hardware store or from IKEA itself.
