I made this SD card holder because i wasn't satisfied by the others i observed in the web.
The box can contain 6 SD cards.
For the magnet i used Ø5x2mm magnet, easily findable on Amazon.
For the hinge's pin i used a piece of Ø1,75mm AISI 316, but you can also use a normal piece of iron or copper wire.
I used a little point of epoxy glue in the two terminal of the pin to pervent the leak from his hole.
I Hope you will find this think useful! Sorry for the photos, but i don't know why i can't upload them in the correct orientation :(
Let me know what you think in the comments :)
