Doublehose plate for mobile AC - EU

I made this plate (around 130cm long) for the my windows. This way I can use the shutters to close the window off for the AC. I used "DeLonghi TL1857" Adapter on the AC side which slot into this plate. 

I did split the original plate into multiple parts. This is size adjusted again and now I am reprinting with snaps and see how this goes. Feel free to adjust this and please credit the original. It is a simple thing I know.
