Recently, I bought two portable toolboxes from Milwaukee, model number 48-22-8435. However, one of them didn't come with internal dividers, so I decided to make a set myself.

Considering that the height of these two toolboxes is exactly the same, I think they should also be a perfect fit for the Milwaukee 48-22-8430 model toolbox.

In the photos, you can clearly see the comparison effect between the original toolbox and the homemade printout.
