doctor who card holder

In need of a Business card holder for work and me being a huge Doctor Who fan this just made sense. This was designed in Tinkercad, I used the sonic screwdriver by Jeremy H published by UpperLakeHighTechnology that can be found here http://www.thingiverse.com/thing:484189/#files I embedded it into the card holder and filled in some gaps to make it easier in printing, then i designed the back to look like the Tardis. This is my first design I published, and there is still some tweaking to do. Hope you like
