Anet A6 Fan Duct "The Warthog"

Just created this double duct thing to get better printing results. It's flat so it's easy to print and use. No need of later processing because of supports.

I printed it with 0.1 layer height with 20% infil. This thing works really nice. Use up to 100% of radial fan speed without too much pressure.

### Important
This thing is created with 10x size. Don't forget to scale it down to 10%!!!
V2 is scaled correctly. Dont scale it down!!!
