I downloaded the XL toolbox by Heath but didn't realize it was still kind of small for all the parts I had. So, I beefed it up to hold 4 trays instead of 2 by making it longer. Had to get creative with the slicer to pull this off, but it turned out great.

I did make an XXXL version as well, that is way deeper and can hold my larger items.

Supplies needed.

2x M3*35 screws for hinges.

2x M3 nuts for hinges.

4x M3*30 screws for latches.
