From the designer:
This is a custom insert that I have designed to fit your Milwaukee Packout Drawers to store your M12 Cable Stapler. It specifically fits the Milwaukee 2 & 3 Drawer units (48-22-8443 & 48-22-8442). There's room to store your Cable stapler, heaps of staple supplies and even two 2.0Ah Batteries. There is staple storage available both under the stapler and in the tub that runs the length of the insert on the side.
This is the specific tool the insert is designed for: https://www.milwaukeetool.com.au/power-tools/nailers/staplers/M12BCST0.html
This is the ultimate modular storage solution for your Packout Drawers! Files are provided for having your insert on either the left or right side. I will have many more designs to share for the drawers soon so you can mix and match your inserts to set up your own perfect drawer units!
BELT HOOK NOTE:
If your belt hook is on the same side as what is pictured above (the right side of the tool when holding it) you will need to print the "standard" files. If your belt hook is on the opposite side of the tool (the left when holding it), you will need to print the "mirrored."
This ensures that your tool sits flat without the belt hook hanging underneath. The tolerances of the 3 drawer units meant that the only way to fit this tool with the belt hook AND have staple storage under the tool was to have the hook facing towards the bottom of the drawer.
