Customizable SD card holder

I found myself in a situation where my tabletops were scattered with SD cards and I really didn't have any clue what they contained. I was pretty sure my vacuum cleaner had eaten more that it's share of my cards so something had to be done.

There are many models for SD card holders in Thingiverse but all I cound find were in one row so I made a quick model with OpenSCAD and decided to share it here.

This model is my first customizable model, you can customize

* number of rows
* number of columns
* height of object
* corner radius
* tolerance which you can tweak so the holes aren't too tight. I have used 0.2mm which gives a snug fit **please note - if your printer is not calibrated you should use something like 0.8mm**

The customization view is a bit spartan at the moment, the Thingiverse documentation is here isn't optimal. However I will try to improve it later when I have more time to experiment with various settings.

Hope someone finds this useful.
