I'm currently modding a 1/43 Corsa B to look like the one that I had.
First thing I want to change the model's wheels, and the one that I had on the real car looked like this:

They're 13" steel wheels, with a center cap.
Any suggestions how is it possible to get wheels like the above? (Or similar)
Is there any tutorials on how to design a 3D model that can be printed? (I searched and couldn't find in the forum)
Thanks.
