2-in-1 fan duct for side-mount fan -Geetech, Euroway

UPDATE- added a V2 duct that is thinner to avoid collision with side post. Still, check clearance if printing a wide part.

The original duct may cause the fan to collide with vertical post at maximum lateral extent. Looks like the part needs to be 1.5 cm shorter in the direction of airflow, hence version 2 was created. But the original duct is left here in case it works better for a particular situation.

Modified for a side-mounted fan like the CTC Euroway. This one has Geetech board
