I'm using a Photon 2 along with a Grove Ultrasonic Range Sensor to monitor the salt level in my water softener. I designed this for a quick and easy way to mount the Photon 2 to the wall.

The solderless mount can be used for quick prototyping. Wire can be inserted either from the outside or inside for a cleaner look. I incorporated a zip tie slot on the inside to firmly hold wires for strain relief. 

There are two cases that are available. The cases are a friction fit over the solderless mount. Both cases have two holes on the top to access the Reset and Mode buttons (via straight pin/needle), a hole for the indicator LED, as well as two thumb slots for easier disassembly. 

One case only has an opening for a micro USB cable. The other case has the USB opening as well as an opening for the JST connector.

Update: V2 of the cases have a larger thumb slot and I had to raise the case height a bit to provide more internal clearance of the plugs.
