I read them as, enthusiastic promoters on the bleeding edge. They jumped into 3D printing despite the risks. Harsh to call that &#x27;greedy&#x27;.<p>That said, 3D printing is still pretty lame. Cheap plastic parts are rarely the critical element in a device. And even knobs etc often have retaining clips or friction-fit holes with sub-millimeter tolerances, that 3D printers cannot achieve.
