About this 3D model

This thing evolved from more experimenting in Groboto. All together there are nine autobots in this design. In an earlier version, I had the sphere free to move but captive in the larger bot. However it never stayed in the best position for the overall design. In this final version, I have anchored the sphere in three locations so it is held nicely in place. Just be careful when removing the support structure that you don't trim these posts away.
