Certainly! I would be happy if you could.
It's a bit difficult for me to describe, since I don't know English that
well, but let's try: I've modeled the centre of the wheel 2994 basically
as a disc with an axle hole in the centre and six 8 LDU diameter holes
around. In the real part, this structure is a bit more complicated.
On the front side, (as I have drawn the part above), there is a curved
surface around the six holes. This surface has a structure such that
the disc is widest far away from the centre and slimmer to the centre.
On the rear side, there are "caves" between the six holes, almost as the
"caves" between the holes in the Technic liftarm parts, say. These
"caves" make the part less "solid", keeping the mass down. They also
increase the rigidity, I suppose, as the area of the surface is larger.
I hope this explanation was good enough. If not, please ask more
questions.
