If you're building on that scale, then make the width 15,000km. That's 
still more than paper-thin compared to the radius, but it's still a 
sizeable fraction of Earth's equator. I'd think the 15km version would 
be claustrophobic, This scale would be more like one of Iain Banks' 
Orbitals from the Culture series.
