Schrader Valve Deflater

I wanted a way to deflate tubes without having to remove the Schrader valve, specifically airplane tubes. Additionally, I wanted to be able to manipulate a tube to fold it into a desired shape without having to fight with residual air, or lack of air in the tube. Print like a cup and no supports needed. I used ABS so I can throw this in my tool bag and not have to worry about heat deforming the shape. PLA or PETG would be fine as well. I also did .10 layer height to ensure the threads printed well.
