Modular Wire Basket Box

This is a modular box for wire baskets.
I made this because we have very limited space at home and had to compress all of our newborns clothes into three wire baskets in a wardrobe.
The annoying thing with that was that his tiny socks kept falling through the holes and wouldn't stay in the basket.

So I made this little modular box to prevent that from happening, and I also noticed that the parts with walls were good for like making small sections in the basket for different types of clothes
