Customizable SD and MicroSD card holder

Basic SD card holder loosely based on http://www.thingiverse.com/thing:15323 with extra slots for MicroSD added.

I've not tried printing it yet. You can edit the scad file in Customizer or OpenSCAD or just print my pre-made STL file.

Update: added a FreeCAD version that's hand-drawn with nice round corners

Update 2: OpenSCAD version with rounded corners: http://www.thingiverse.com/thing:1751902

Update 3: fixed microSD orientation in scad version so its portrait not landscape
