ToM third dino

The Z stage of the Thing-o-Matic has 2 unused mounting holes in the back.
Yet it only supports it's heavy extruder from the left and right using long levers.

When transporting the ToM in a vibrating vessel, maybe even non-upright, there is lots of stress on these tiny bolts.
(Think of having it on it's back in the overhead compartment of a train.)

So I'm testing this to support the extruder stepper from the back with a third "dino".
