RC522 Simple Case

thingiverse

Here is a simple case for the standard RC522 cards. This one prints easily, and mounts securely to a surface using two flat head screws. Printing should be straightforward. You will need four 3mm brass knurled inserts for the back screws, and four 3mm by 8mm flat head screws for the rear. The front can use longer 3mm flat heads to attach the board.
