The Pass-pirator aka Car Window Forced "Air Conditioner" Vent

Do you get hot in your car while driving? Do your passengers complain about your weak A/C?  Do you want to experience the thrill of having a leaf blower aimed at your head while on the highway? Or maybe your A/C just broke and you're looking for a quick and easy fix in this heatwave?Look no further! Introducing the next generation of high-performance automotive passenger cooling technology: The Pass-pirator!This device installs in seconds by placing the vent into an open window and simply partially rolling up the window to lock into place. It fits in any car window and works by just driving around! The aerodynamically engineered (not really lol) scoop funnels cooler, faster moving air from outside the vehicle to inside, where the passengers can enjoy a refreshing breeze at any speed (above zero)!In all seriousness, my car does not have A/C (previous owner took it out for some reason???) so this is a lifesaver for me. I took inspiration from older vehicles that have the windows that you can flip forward to achieve the same effect. This will work in all conditions without any need for electricity but it will suck up rain, smoke, and smells along with the air so be aware of that. I have tested this up to around 85mph on my car with no issues but I would HIGHLY RECOMMEND A SAFETY ROPE so if an event of rapid unscheduled disassembly occurs, you won't lose anything but your pride. Tips/troubleshooting:IF YOU'RE GONNA STICK ANYTHING OUT THE WINDOW MAKE SURE IT CAN'T FLY OUT. I use a short piece of rope tied through the whole thing and the other end is tied to my passenger seat headrest.This model requires a decent amount of support and removing it can be a pain so go slowly and take your time.In the pictures I have zipties around the ends of the main body because I accidentally split the print when I was putting it together. I would add zipties anyway because the torque from having the scoop out the window at highway speeds is definitely not great.I keep it installed on the passenger side because having this and the window partially open on the highway is loud.I used paraffin wax to lubricate the scoop but that ended up making too loose so it would point straight down. I fixed this by making the safety rope tighter and that holds the scoop mostly in the direction the car is facing so it's fine.Please excuse the glaring issues with the models symmetry, I know they're there but I designed it as a quick fix and it worked so I'm probably not going to change it unless it breaks.Lastly the print in the pictures looks terrible because it was printed with lightning infill (only 3 perimeter lines) and with very little support. I was almost out of PETG, don't blame me
