Add screws to bottom cover

Let's start by fastening two #4-40 3/8 flat Phillips machine screws into the two holes on the bottom cover part [not the holes in the corners]. Fasten until you see the screw thread slightly protrude the top of the stand-off - so, not all the way.

Mount Micro USB Lipo Charger to bottom cover

Let's mount the micro USB lipo charger to the bottom cover. Place it over the stand-offs with the machine screw lined up with the mounting hole on the lipo charger PCB. Make sure the USB charging port is facing the outter edge.  Hold the component firmly in place while you fasten the machine screw, all the way.

Mount Bluefruit EZ-Key to bottom cover

Next up, we'll need to mount the Bluefruit EZ-Key to the bottom cover. Let's do the same song and dace we just did for the lipo charger to the Bluefruit EZ-Key. Note, the mounting holes on the Bluefruit EZ-Key are just a bit smaller than the micro lipo charger, so you'll need to loosen the hole if the #4-40 machine screw doesn't go in. I used a sharp and pointy #4-40 screw to tap the hole - it just barely broke the PCB because the mounting hole is small, so do it slowly and carefully.

Mount Bluetooth Pair button to bottom cover

There's a small platform for the bluetooth pair button to rest on. You may want to bend the leads apart. Add a dap of super glue to the top surface of the platform and then quickly place the button on top, with the button facing the outter edge. Allow glue to dry before proceeding.

Mount Perma-Proto to bottom cover

Now we need to mount the Perma-Proto PCB to the bottom cover. Carefully coil the input wires underneath the PCB and place it on top of the two tall stand-offs. Line up the mount holes with the stand-offs and hold the PCB in place. Insert two #4-40 3/8 flat Phillips machine screws into the Perma-Proto until it's fastened to the stand offs. Fasten all the way until the PCB is completely secured.

Insert circuit into case

Place the circuit into the enclosure at a 45-ish degree angle so that the Perma-Proto PCB goes underneath the clips on the inside fo the enclosure. Ensure the micro USB port on the lipo charger is facing the cut out on the encosure. Carefully slide it into the enclosure, but don't close it completely, yet!

Install slide switch into case

With the circuit half-way inserted, pull out the slide switch from the circuit and press it down into the cut out for the slide switch. The clips will hold the switch and prevent it from being pushed all the way inside the enclosure.

Once the slide switch is inserted in place, close up the bottom cover!

Add cover to top case

To finish off this project, you can add a cover to the front of the enclosure to change up color scheme. In this project I used a black color to add contrast to the pink enclosure. You can apply adhesives like E600 to the parts for a perminent seal, or you can use funtac like I did.
