Peter has used the Transparent Bright Green version (Element ID 6139234). Only the shaft end is visible, creating the robot's eye, but the piece is critical to the build. Peter kindly sent a breakdown picture to explain things clearly.
Threaded onto the shaft, an 'Apollo stud' (round 1x1 plate with open stud, Design IDs 85861 and 28626) is used to attach an interesting Dark Stone Grey piece I am unfamiliar with. Peter was none the wiser, really... "something from Star Wars, I think. I need to have more" was all he said. I'm sure one of you readers can help!
I love how a little bit of green light happens to catch the indentation on the 1x2 ingot tile (99563), making it look a bit like an illuminated panel.
