That's what I did.

1. Step 1:

   phi=2*atan((1+sqrt(5))/2)

   rad=a*(1+sin(18))

   a=100

   Draw pentagon, where a is a radius of circumscribed circle.

   Create auxiliary datum plane passing trough the rib at an angle equal to the parameter phi.

   Draw second pentagon.

   

2. Step 2:

   Make surfaces of them.
   

   

3. Step 3:

   Do array
   

   

4. Step 4:

   Do copy five surfaces with translation by the amount equal to parameter (2*rad) along Y-axis. The axis Y - perpendicular to the plane of the first pentagon. And rotation axis Z and X on180° and 36°, respectively.

   

5. Step 5:

   Combine surfaces and do displacement inside.
   

   

6. Step 6:

   Closing volume with surfaces. Make solid detail.
   

   

7. Step 7:

   Round, round and round.
