Business Card Holder - Printable

I liked the business card holder ( https://www.thingiverse.com/thing:137636 ), but it isn't printable. My version isn't perfect, but can be printed. It isn't really a re-mix per say, but it is in spirit (I started from scratch on my version). Should work without any scaling for standard sized business cards, don't overfill it or it could become top-heavy (Perhaps consider taping it down)
