There's nothing like housing your modern technology in the facade of old technology. This is a small laser cut box that can hold up to 8 full-sized SD flash cards. There is a small living spring that will hold the lid shut when it's bouncing around in your bag. You can open the box from either side.
With Christmas coming up, this would make great easy to make gift. I know I'll be making a set of them.
This holder is the second generation of a SD card box, the original version was not nearly as much fun.
Update 05/14/2016 - It's been almost been 5 years since I posted this, and have uploaded the latest version of my cut files. Thanks everyone for your interest.
