Dual Cooling Duct

This is a removable mount since I mainly work with ABS and don't use cooling. Since I've modified my AirWolf XL3D with a 2nd Budaschnozzle I need cooling options since I plan on running multiple materials in the same build for example ABS & TPE or ABS & PVA Support material I need the option to independently cool each nozzle.
Uses standard 40mm fans with 3mm nuts/bolts.
