A box to contain an arduino nano connected with a rc522 rfid module.
Not Fully satisfy by Dgoma box design (http://www.thingiverse.com/thing:1413827) I decide to make my own.
Like Dgoma I could only recommend the Miguelbalboa's work for the arduino programmation (GitHub: https://github.com/miguelbalboa/rfid)
There is still improvement to be done (mainly on external aspect) but it's full-fill its function to hold everything in place without screw or glue.
Printed from a PLA roll I need to finish (never succed to obtain a good aspect with it)
