I've always been a loyal fan of Milwaukee Packout toolboxes, but I've always regretted that they haven't launched a tool rack specifically designed for wrenches. So, I decided to take matters into my own hands and solve this problem! These wrench racks are specifically designed for use with Packout low-profile compact storage boxes

Although there are no particularly recommended printing parameters, I suggest setting the wall thickness to 3 layers or more to further enhance the structural strength.

For easy and flexible adjustment, the tool rack adopts a split design and consists of two parts. I used hot melt adhesive to fix the tool rack on the Packout storage box—the hot melt adhesive is easy to apply, and it's also effortless to disassemble if you need to readjust the spacing. Of course, other types of adhesives can also be used.

In addition, it is recommended to pad the inside of the storage box lid with a layer of cushioning material to effectively prevent the wrench from shifting due to shaking when the box lid is closed. Self-adhesive foam strips for windows are a good choice. They are soft and durable, and can play a good cushioning role.
