3 Layers Block Letter

This project was one of the most difficult for me since I'm not very familiar with 3d objects in paper.  I hope to be less busy next week so I can re-start learning more about the machine and software (by the way, this block letter was designed using illustrator and then transfered to the pazzles application.  

A few days back I saw that Pazzles has an illustrator extenssion...does anybody knows where it is?
