Metal Collapsable Crate Fan Hanger/Bracket

I have a metal collapsable crate that I keep in my office. As I cannot control the temperature, I decided to add a fan for my dog's comfort. I used a fan I purchased off Amazon that I had previously purchased for another project. The fan offered by the crate manufacture was out of stock and cost $75. My dog also likes to chew on anything inside the crate so that was not the best mounting option. This was a quick and easy solution. I have a Rock Creek Crate, but it may work well on an Impact Crate or other brands.

This is the fan I used
