Tevo Tarantula Dual Blower Fan Duct for E3DV6 or Volcano + Titan for Direct or Bowden

Here is my E3DV6 dual blower fan duct system for the Tevo Tarantula
using a E3DV6 hotend and Titan extruder in either direct or bowden
configurations. The blowers are standard 5015 radial fans.

I couldn't find any dual blower fan ducts that were easy to print, had
individually adjustable heights for each fan duct, and were usable with
a E3DV6 and Titan extruder in direct drive mode. I also wanted to be
able to change fan nozzle types easily without having to disassemble the
whole thing
