The Raspberry Pi 2 has one major flaw that I ran into - the SD card is spring loaded catch, rather than just the friction fit like the RP1 3 and 3 B+.

When the spring mechanism failed, I was inclined to throw the Pi 2 out. So I played with a design to have two pegs sit in the holes and provide a friction fit for the micro SD card.

Next iteration will likely include a proper case that incorporates this design - but it will need to snap together so the card can still be replaced/upgraded without tools.

Not a precision fit - this was a quick draft project I did to get the Pi up and running.
