Back cooling Duct for Creality Sprite Extruder, Dual 5015 Fans, Ender 3 S1 Pro (not enough space, not working)

v.2 Started working again on it, created an initial print to see how it fits for the space, fine tuned but in the end the space is just too small, too many sharp corners and the air flow in the end will be unequal and not that high.

An alternative would be to decrease the print area so i have more space for the duct but is a big drawback.

In the end i see this as a dead-end because of too many disadvantages.

I've attached a model of the maximum space that is available for the duct to see it for yourself UnderBFarea. 

v1.  From the request of @AndreiX_442139 a new cooling duct with improved visibility, it allow the extruder motor to keep cool and moves the center of gravity towards the mounting plate.

Untested!

Please check the travel to make sure it has free run and activates the home sensor before powering on.

Feel free to ask me anything.

Any ideas and improvements are welcomed!
