Ever had someone question your ability to differentiate between Dothraki and Klingon? Ever have someone assume you need help configuring your wifi settings? Ever had a kid try to explain to you the concept of a sonic screwdriver?

Well I have, and there is nothing worse than having your Nerd credentials questioned. That is why I invented Nerd Card. Nothing says, I'm a Nerd, like pulling out a 3D printed Nerd Card.

Nerd Card is the size of a credit card and slides easily into a purse or wallet. It doesn't matter what type of Nerd you are, there is a Nerd Card for you. Go for the Original Nerd Card, 8-bit Nerd Card or the Sci-Fi Nerd Card. The only way you can go wrong is by not carrying one.

The 3 Nerd Card designs comes in a plastic saving Cut Out version perfect for stenciling a bulkhead, blaster or computer case. The Nerd Card also comes in an engraved version designed for 2 color prints. Print a Nerd Card in your Pyramid or Quidditch team colors. Be proud of who you are. Show the world that you are a Nerd!

I'm publishing the Nerd Card designs to celebrate the first anniversary of my blog, designmaketeach.com, and Twitter account, @DesignMakeTeach.

I'm also giving away a physical copy of the Nerd Card to a lucky reader http://designmaketeach.com/2014/04/15/happy-1-year-reader-give-away/
