How to Use
Using this is pretty simple. First print both parts. Screw the largest part down so it's facing the sample field. Slide the phone in so that the camera is in line with the slot.
Then, slide the second part (The Bar) into the slot to lock the phone in. Plug the phone in, and give it a shot!
