Yet Another SD Card Holder Remix

I really liked the simplicity of cmh's design, but I needed a little bit more storage space, so I added a third section for the SD cards. (A huge thanks to cmh for uploading the Sketchup model he created. I made sure to do the same. This was my first time using Sketchup, but I found it pretty simple, although I'm sure a more experienced user would have been more efficient than I was.)

The other change I made was to increase the depth of the slots for the microSD cards from 6mm to 11mm so they were protected a bit more.
