AIr Conditioner Exhust Bracket Extender

My portable Air Conditioner Unit has a hot air exhaust pipe that goes out the window, but the bracket that fills the gap in the window is to small. SO I decided to print something that would fill this gap so the hot air would not come in while I am trying to cool the room.

I used Sketch-Up to design this part, and if I did it again I think I would design it differently, but it is doing everything I want it to do..

If you want to see how I created this part then watch my video on YouTube. https://youtu.be/06DNRgwMgAI
