X1c Vent System v2

This is my second version of the X1c venting system. This is MUCH quieter than my first one. It uses three inline booster fans spaced for pressure stacking, with a single flow straightener between the second and third fan to reduce swirl and noise while improving effective static pressure. There are two options to connect: a HEPA filter end or an exhaust pipe for venting out a window. Magnets allow you to swap these quickly. Assembly: The Noctua fans come with a lot of extra cables, so you can use those to connect all three fans to the controller. There is one honeycomb spacer that should go after the 2nd fan (between the 2nd and the 3rd). This will strengthen the air to both help with drawing and quiet down the exhale. I didn't need glue for the magnets; they just pressed in.
