Volvo B230 8v Throttle Body Flange

I made this model so I could make an adapter to fit he 8v intake manifold, but I wasn't satisfied with how it would be sitting on it.

It is a functional part, and I didn't bother making the whole throttle body as I did not need it.

16v throttle body accepts a 3" hose, while having an inner diameter of 65mm.
8v throttle body accepts a 2.5" hose while being 55mm in inner diameter.

The 8v intake manifold inlet hole is 59-60mm though, depending on the casting.
