Step 7: Teensy and USB cable and the casing
As you can see in the picture there's not much room in here at all. You will need to cut the USB cable thread it though, and then resolder it. At this point you should have everything attached now the fun part...putting it all together. It took me about 30min to figure a way to get everything in there and having the button still operate. One tip is the screws you took out from the inside, they dont get put back in. The only screws i used were the 4 on the bottom, the rest is so tight though theres no need for them.
Make sure you have the reset button accessible from the battery door so that you can program the button after its together.
