Bondtech BMG-X2 40mm Part Cooling Fan Duct Assembly. (Abandoned)

This is a design I've been working on for a couple days since I couldn't find any good, narrow width parts coolers for the Bondtech BMG-X2 that wouldn't collide with my z axis parts. It uses three 40mm fans, the two outermost ones connected together to cool off the extruded plastic, and the center one to cool the cold side heatsink. It mounts with four m3x10mm screws to the heatsink, and the fans all mount with m3 up to 30mm screws. I am not sure how well this will work compared to blower designs, it should draw in fairly cool air, but doesn't push as much as a blower fan. It does seem to have a nice even flow of air around both nozzles, and without too much updraft cooling off the heat blocks. I do not have the BMG-X2 mounted on my printer yet so I am unfortunately unable to test it at this time. I'll be updating this actively as I manage to test it, or get feedback.
