Just some bins to fit inside this organization case to give me more bins for smaller parts as well as keep washers from sliding underneath the original separators. Plus it is nice to grab the bin you need instead of the entire case when you need a lot of one thing.

One cell means it is one bin per divider area.
Two cell means it is two bins per divider area.
Four cell means it is four bins per divider area.
