Soldering Fan to 2020 Extruded Aluminum Holder

I got sick of having a fan just sitting on my desk all the time and falling over or always in the way. I outlined my desks with 2020 extruded aluminum and thought this would fit directly on top. Turns out it seems to work well for my use case. Sharing in case someone else wants something simple. 

Here's the fan:
