3D Printed Supercharger in Polycarbonate makes 5psi at 50,000 rpm and explodes in my face. Built this a few years ago, reckless mistake, but worth sharing. from 3Dprinting

Before reading, gonna bet that he didn't account for deflection at speed and got some rubbing till boom.

Edit: Nope, guy sounds like he has his engineering head on straight. This appears to be a wobble at high speed from the unsupported end of the shaft due to an imbalance in the print.
