This is designed to fit into the Dewalt Tough system storage boxes. My coworker and I use these for our sheet metal tooling. We store, transport, and work out of these boxes and trays. This is a great size to fit your pliers, rulers, scrapers, alignment picks, and cold chisels. The inside corners are filleted to help keep items from getting trapped in the corners. This length will fit normal sized hammers and dogleg deburring tools.

For this print, you need to perform a cut at the middle point (6.39 in) in your slicer to make it fit on your bed. The second file is the splice to reattach them. It has the necessary gap to ensure a proper fit into your box with no wasted space. It has 2 12.5mm flanges to glue the entire unit together. I printed in 2 different colors to show contrast.
