Modelling of cast disc
Part 3 (Nuts)
I decided to do low-poly nuts on the central part outer perimeter cause it'll save many polygons. From the cylinder(above 20-30 sectoins)create such a form:

I think it's not hard to do it yourselves. Then put this nut accurately into the disc center.

Now apply Array to the nut with parameters as in the picture.

That is all, perhaps.
