Airfoil Turning Vanes Air Vent Deflector Louvers (Fixed Angle)

thingiverse

Attempt to redirect air from hvac register without pressure drop. Fixed at around 45-50°. Industrial versions that go inside 90° square ducts are said to be 800% more efficient than just the bare 90° elbow. Thrown together in sketchup, roughly 200mm wide by 160mm tall. Thanks Parkinbot for the airfoil, not very scientific airfoil choice, it just looked right for this. I set slicer to 4 perimeters and 10% infill so the vanes would print strong and hollow
