I have lying around these SD card reader/write usb sticks.
Many people must have them, because they are free with many cheap printers from china.
But they are not very handy to use, because the card goes in so deep that it's hard to get them out again.
So have cut a part of it's housing off --> see picture :-)
Then the card reader man came into my mind. :-)
printed in ABS and it can also hold 7 micro SD card's.
Head and body are fitted with little screws, but you can also glue it.
His right arm is glued anyways :-)
PS:I recommend that you print the arm with a BRIM. I used a resulution op 0.2 mm but this object is so small, that you might want to go for 0.1mm :-)
