Tevo Tornado Round Fan Duct for 5015 Blower

This is a fan duct for 5015 blower on Tevo Tornado. I created it in a purpose to make as little modification as possible on the Tornado. The only thing that needs to be replace is the cooling fan and some additional screws and nuts. Also, the outlet has been designed to direct air to gather right below the nozzle. It should improves your overhang print a lot as seen in my overhang test (ignore the stringing, I haven't tweaked it properly ;P).

Additional parts:
1. M3 Pan Head Hex Socket Screw
