120mm fan to 1.5" tube adapter

I print a lot of parts inside my house and leave a couple windows open for ventilation from the plastic melting vapor. Unfortunately, when it gets cold out, I don't want to open all my windows so I'm building a fume extraction system. This is a key element and it couldn't be more straightforward. I hook a vacuum hose to each side and can now quietly draw the fumes from my 3d printer out of my window. Let me know what you end up using it for.
Enjoy!
