but the bones are ONLY in X3G format, which of course means you can only print them on a Makerbot.

Hi Jeff, the Replicator 2, Flashforge 3D, Duplicator 4 and basically any of those similarly cloned machines will read X3G just fine. They also use Makerware and trick it into thinking it's a makerbot.
