Hood Canon EF 10-18mm with 67mm thread

Here is my second project.
A lens hood for a Canon wide angle lens EF- 10-18mm with 67 mm thread.
The aperture I have made because with normal lens hoods always left and right margins on the photos are visible. Here I have changed the angles so that the Blend even with full zoom is not visible in the picture.

Construction size:
Mount 75mm
End 95 mm
Height 30 mm
