BigBox Hybrid Dual Fan Shorter

My copy of BigBox Hybrid Dual Fan Alternative by GregoryHolloway printed in black Edge filament was wilting in the heat between the two hot end blocks. I decided to try and modify the blower ducts to provide a shorter, straighter path to both nozzles. I'm still testing it out but it seems to work well so far. Still uses the standard BigBox Hybrid mountings and 40x40x20 Blower Fan.
