Thanks for a very clever tut, LuxXeon :)

Here's my take, done in Hexagon in under a minute - most of which was spent selecting individual facets.  BTW, the Hex equivalent of Blender's "remove doubles" is "average weld" and in Hex you can specify the number of tessellations - cuts - at the point of insertion.  The extrude tool is admittedly scary when first using it, with geometry exploding all over the place, but it is easy to get them under control with delicate movements of the mouse :)

Been using Hex for many a year and never thought I'd bid it goodbye - until getting into Blender!  Now Hex is pretty clunky for me.

One thing I do miss about it are the surface modelling tools - Ruled Surface, Coons and Gordons.  Drawing out splines splines and joining (lofting ?) to form surfaces. Beveling Bezier curves and possibly Nurbs are about the closest I've come across in Blender so far, but not quite.

I'm still very much on the early learning curve in Blender and would love to know from experienced users what equivalents to these processes Blender has.

Edit :Oh dear - seems I can't post a pic!
