Lego Arduino Nano Without Header Pins Housing

I needed a housing for my Arduino Nano that doesn't have any header pins soldered to it. I wanted it nice and small.

The gap is there to allow the arduino to fit nicely and have access to the reset button.

The "Handle" piece at the back keeps the arduino from sliding around too much.

You could use a 4x8 piece for the bottom, but this allows you to have some wires come out the bottom if you need a few pins connected.

The little ramp pieces keep the arduino nice and snug. Note there is a 2x2 piece under the top to keep the USB tight while the cable is pushed in.
