3D Printed Business Cards? Why not?!

It seems engineers like to joke about turning junk parts into business cards that they can hand to customers and clients for fun.  I decided to try 3D printing business cards.  Its fun, novel and sure to get someones attention.

Rev A was a little plain but more a proof of concept.  I had some fun with Rev B, the gears really make a statement and I like having parts stand out off the surface with some elements that cut through the card.
