First Attempt: Working with a fellow engineer who knows more about CAD than I do, we decided to use a two piece design that would sandwich the electronics and battery. We'd 3D print the two pieces of the enclosure and hold the whole thing together with four small screws. As you can see below, our first design ended up being pretty boxy.

|Revising the design to make it slimmer and easier to slide down into a pocket.|
|The opening to expose the SD card isn't attractive, but it does work.|
|Our final design. Download it from our GitHub!|
