This is an updated version of my “Locking Wall Mount For Milwaukee Packout”. I took inspiration from Sean&Lucia's Packout mount on Printables (https://www.printables.com/model/357256) but completely rebuilt it using my easy alignment method.

This new version can fit a plate that holds all 6 feet compared to only 4 before. It also uses less material, no supports, and prints faster (I also think it looks a lot nicer than my last design) I also included a removeable locking tab in case you need to make sure your box won't fall out of the mount. This mount does hold the boxes fairly snug without the locking tab though as you can see in the last picture where the box is upside down. The mounting holes were designed for regular drywall screw, but you may be able to use other screws as well.

Please note that the licensing doesn't allow for my file or prints of the file to be sold
