If you have ever had the problem of a window air conditioner blowing cold air directly on you then this part is for you!
It adheres to the front of your air conditioner and blows air up instead of out. Especially handy for when your bed or desk is directly in front of the only window in the room!
I have a YouTube video describing how to design and install it here: https://youtu.be/YxF37F8xGhA
You can follow the same steps for a different make/model.
This design should work for all the ACs in LG line that are similar to the one shown. For example, the 8-12K BTU units here: https://amzn.to/2K2YsoC
Infill doesn't matter, just make sure that you are getting decent coverage on every layer
