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
