Mask the body cap so only the aluminum disk is showing.
Alternatively you could use the sharpie marker to paint the whole disk and masking in that case would not be required. However painting with a flat paint works better.
Here is the finished lens. From here if the hole is too small (a lot of refraction - take a photo of something bright white in full sun and look at the edges) you can carefully use the needle on both sides of the lens to round out the hole larger. Do this in small incremental steps so you don't oversize the hole. Once the hole is too large there is no way to make it smaller. However making a new aluminum disk is easy. Just replace the disk with a new one following steps 4-14.
Here is the taping done for the final stripes. Because these stripes were going over the existing orange diamonds, we had to tape both sides of the stripe. I used, again, the tape-offset technique to get a reference center stripe and then used smaller pieces of the tape to measure off the outside tape-lines.
The crosses were particularly fun to do - which is in the next photo.
Slowly drill (or hand twist the bit) a hole in the center punch dimple. Clean up the edges so they look smooth and there is no jagged edges around the hole.
Mark a dimple in the center of the body cap with the center punch tool. A nail or similar tool will work also.
Carefully tape the aluminum disk to the body cap ensuring the pinhole is still centered in the 1/4" drilled hole. Allow adhesive to completely dry.
Here you can see that we have pained the purple stripes as well. Unlike the pink, the purple stripes were not going straight down the center of the green but off-set to the side a bit. Also, you can see where I have feathered the green over the diamonds, feathering like this makes for better tape lines and less bleed. It's even better if you can feather in the colour you are painting over (so feathering in orange, in this case) but the orange was from the previous painting of the room and so we didn't have it available (and I didn't really think about that idea until after this project was basically completed).
After coloring around the pinhole with the sharpie marker it's time to remove all the masking tape. Your pen painting should be darker than mine as the marker I used was not very dark.
Using a White Two-Way Nail art Pen/Brush make little white dots in a diagonal pattern along the top left of your nails. They can be big or little dots, don't worry about them being perfectly even.
