Genealogy / Archeology of the Greg's Wade's Geared Extruder

In this page I will illustrate (to the best of my knowledge) how the original design for the Wade's geared extruder has evolved in the last few years. Nowadays (early 2015)

1st Gen: Wade's original design

This is actually documented right here in this wiki: Wade's_Geared_Extruder and you can find all the files for it on that same page.

Now, I understand that the original Wade's geared extruder from February 2010 is itself an evolution of an earlier extruder design by Adrian Bowyer and also includes many ideas from Nophead's early research on extruders. It seems it was not designed in OpenSCAD and I don't have any information on what CAD program Wade used.

All the files for this extruder are available both here on RepRap.org and also on Thingiverse (link).
