Rear Derailleur Hanger Banger for a 12mm through axle?

I am tired of bending the hanger on my bike. I went through a couple of threads and saw some of you talking about the Hanger Banger and that seems like the fix for me. Only problem is that John Henry's does not seem to offer one for a 12mm axle. I usually just bend it back once or twice until I start seeing stress marks in the aluminium. But re aligning them over and over on the trail is just old. If any of you know of something comparable for a 12mm axle would be geat. And yes, I know should watch out for stumps and rocks and stop crashing but that is probably not going to happen. Thanks.:madman:
