Time to finish up work on the eye. All that remains is to glue the opaque lens in place.
I am using GE Silicone II to glue in the lens. I did the same for droid #1, and the lens has withstood three and-a-half years of poking and prodding without coming loose.
On goes the silicone.
I smeared the silicone around the edge, and I'll let it dry for a good 24 hours or so.
