E3D V6 split fan shroud

I combined a 30mm fan duct with a filament cooler duct.
I am taking about one third of the air from the heat sink and diverting it to the filament on the bed. I wanted to minimize the weight on my effector and I wanted to cool the heat sink and the printed material with one fan.
I got tired of this thing breaking when I snap it on and off so I added a rib on the sides for some extra strength.
There is a tiny 5mm brim - trim away post print.
And the screw holes for the fan should be drille
