Folger i3 2020 Double Print Fan Assembly

I took Pjvpjv's arm and funnel and remixed it a bit so the FolgerTech i3 2020 can fit 2 funnels on to the extruder.

What is different about the original files is that the arm has a ~9mm increase on the left side so that the funnel can be on the same angle as the right side. This is because the left funnel would point ~9mm away from the nozzle before the modification. As for the funnel, I just made the STL contain two funnels, rather than just one.
