I don\'t know where you live, but I actually think you might run afoul of copyright laws here in the U.S..
While it would be really grotty of them, GW does have the right to say \"our business model depends on the fact that you would have bought another model kit for the extra wheel - had you not illegally cast your own.\" You could face both civil and criminal charges if they went that far.
But for a bike wheel? I doubt they\'d do it, even if they are allowed to.
