112 is a good start. I'd like to see the horizontal and vertical lines outside the gear. Also try doubling the number of teeth and make the teeth slightly smaller.
#116 The version with the horizontal and vertical lines outside the gear, also I've added the number of teeth and made the teeth slightly smaller. How about with this one? Thanks...
Not sure about the eyeball in 151. And maybe it's my early-morning eyes but the reticle wire lines don't appear centered in the notches. I'd also like to see what it would look like with the wires extended out past the gear.
