I have a vent directly under my computer disk and it tends to freeze my legs in summer when the central air is on.

I designed this vent plate to shoot the air out the side so that it hits my computer tower which is more beneficial. In winter I can just switch the direction to shoot the heat away from it.

It's a fairly long print and you need at least 280mm to print it in one piece, so CR10 or large build bed.

I printed mine on a JGAurora A5 standing up.

Note: My print in the photo was stopped prematurely due to noise complaints but it still worked fine it's just missing the lip at the open end.
