A tip to remember which screw is which as the differences are pretty tiny: I used different colored sharpie fine-points and made a mark on the top of the screws before removing. I thought about having strips of tape that I stuck similar sizes to, but the coloring seemed to work more easily. I only did this for step 11 and it saved me down the road when trying to differentiate the 1.2 and the 1.3mm screws!
