Bulldog XL / E3D-V6 cooling fan mount (60mm)

I needed to cool the filament exiting my extruder, so I designed this fan duct. Fits for the combination of bulldog XL extruder and E3D-V6 Hotend, snaps directly onto the extruder.

Added a delay timer circuit so the fan required on the E3D-V6 hotend doesn't block the single fan control channel, so it can be used for this thing here. The circuit switches on when the hotend gets power and switches off after it is left without power for like 10 minutes.
