Some more developments. The Z axis and printing head will be supported by a cantilever arm from a sturdy post. The post is made of 2 boat seat pedestals, because they're ideally shaped and very stiff.

You can see here the extruder is made of lego too - driven by a Technic motor. This will be covered in more detail later, when I've tested that it works. It works like the later Mendel extruders, pinching the plastic feedstock between a pair of Lego pulley wheels.
