Based on the thing http://www.thingiverse.com/thing:1748452 from Brainrelates.
I made it customizable and added a few things like a label and rounded edges on the outside.
You can set number of cards to store, type of card (mini, micro, standard) , wall thickness and add a label. You can also add some space to give a little of play to the cards.
- added holes in the bottom so you can push out the sd cards should they get stuck.
- added options to change the dimensions of the sd card in case your sd card happens to be a little bit bigger then the dimensions I found on the internet
0.4 mm or lower resolution
