Arduino Pro Mini Enclosure

This Arduino Pro Mini enclosure has treated me well in various projects. The AA batteries snap in and out and hold in place well. The Arduino can be placed in at an angle and then pressed down to snap into place and held by friction. This allows you to attach and detach a FTDI device for re-flashing without causing the Arduino to be pushed and pulled everywhere. There are also spacers at the bottom to prevent the Arduino's built in reset button from being pressed if put in facing down.
Demonstrated in the pictures is a 3.3v Arduino Pro Mini, a RFM69HCW module, and a reed switch to create a cheap wireless door or window sensor that can run on batteries for several years once you alter the Arduino a bit. All you need is the magnet to pair with it.
The battery contact plates are the super cheap ones online when you search for "AA Battery Positive Negative Conversion Spring Contact Plate". One of them is snipped into two pieces to be properly separated.
