That's not a problem. At all.
Make a bevel for it:

Put that bevel into the bevels file in Application folder > Adobe Illustrator > Support Files > Ressources > [Locale]
Read the instructions in that file and act like described in there
Quit and restart
Apply Extrude effect and enter the dimensions of your custom bevel like so


Et voila:

I still beleive that this should just be taken as a template to make a proper illustrator using gradients, blends, etc.
This 3D object will result in a gazillion of vector paths in the output file.
