I think my brother said it is for the hood, it wasn't for any safety related component anyway.
Not sure it took me exactly one hour, could have been a little more. But I am fairly used to the CAD-program so with a digital caliper it does not take that long to do this kind of object, it has a lot of symmetry after all which makes it quite easy.

Well, as always I start by trying to find symmetry to decide how to draw the component in relation to the datum planes to get away with as little work as possible
(This is why I simply can not take CAD-programs which does not clearly show the datum planes, or even worse, does not have datum planes
)
In this case I started with the thing with the round hole in it, made it with the revolve tool.
For the straight part with the strange shape cuts in it, the cuts have lots of symmetry. So by making new axis and planes and using those as a reference one can use patterning and mirroring so that one has to draw things only once.
It is so much quicker and easier this way than drawing things twice, especially if you need to do changes.
The tooth are also made in a mirror/pattern operation of course
In the end I added lots of rounds and chamfers to remove sharp edges.
The whole component is basically 10 features, two cuts cuts to simplify the design job and the rest is rounds/chamfers:
