Horizontal 4028 fan duct for Narrow-EVA3

If you are using:

• a 4028 part cooling fan
• Squirrelbrain's FBS/Narrow EVA3 mod

Then you need this fan duct, especially if using an x-axis dragchain like Squirrelbrain's mod for the RatRig V-Minion.

UPDATE: I've added a seal that you can print in TPU to avoid most air leaks.

It's mostly horizontal, and it is sturdy and stable. I've tested it in my V-minion.
