This is a 3D printable SD to micro SD memorycard adapter. I used 0.2 mm copper wire to make the contact surfaces according to this image http://1.bp.blogspot.com/-CVibVn3I85w/T_gQL2HT2RI/AAAAAAAAADY/YkTdbAXQuFo/s1600/SDpinout.jpg
You can find the detailed istructions from instructables: http://www.instructables.com/id/3D-printable-micro-SD-adapter/
You should glue the pieces together even tho the bottom piece stays put pretty well on it's own.
My succes ratio on using this isn't too high, probably because the micro sd card is being held on it's place only by friction, but when I got it to the right position it cinnected and i could read the files on the micro SD card.
I'll be working on a better version of this and see if I can make it work 99% of the time.
All credit for the base of SD cards goes to bathrobotics and his SD card dummy:http://www.thingiverse.com/thing:659681
I'm not sure if wiring it wrong could damage your micro SD card so use this on your own responsibility only!
Files have been updated. Now the micro SD card stays on place better and the bottom part fits better.
