Cardosseum (Card Colosseum)

We have an area in front of my shop that I've always wanted to make my own business card holders to put them on display for companies we work with or just have good relations with. So after the card holder contest came up I put some extra thought into it and came up with this. 

I don't have enough time to do a test print, but the thought is that the multiple mounting points will allow it to adapt to a curve to create a colosseum looking card display. 

There are 4 models, the front, the stackable, and a stand for 2 and 3 teirs.
