How would you model this?

Good day.
so I am practicing to model some items I usually not do.
most of what I do is mechanical simpler items.

Correct me If I am wrong
red and orange shapes then network?
how would I tackle the blue part?
the purple I am guessing draw the shape sweep, then cut the front part?

Tnx!
