Bilal, what's your question?
This should be pretty straight forward to create this part in inventor.
10 min work. Kinda sloppy sketchup project, but dimensions should be correct, I grouped each fold separately, the diameter of the rounded edge is little bit off, circle was smaller than the edge itself to be rounded with so I used half-circle with 2,5mm bulge instead.
