Ryobi Charger mount

I had a few Rybobi chargers that I wanted to clear off my workbench and my pegboard wall was a little full. I have the side of a full size refrigerator that was empty space, so I created a mount to magnet the chargers to the side of the fridge. The larger mount in the image is my first pass at a design. I realized it was just wasted filament building the walls around the charger. I ended up printing with 100% infill, with PLA. It seemed sturdy enough to not snap when putting the charger in place. I did notice that the larger 4 hour battery would make the mount slide down the fridge, so I might need a stronger magnet or at least two magnets would be fine. The magnets (36mm x 7mm) I used were from Amazon.
