I've fixed the Mono-Eye of Z'Gok.
I will enclose from the back side of the pipe with epoxy putty units Mono Eye.
There is also a sense of the light-shielding.
I also fixed plastic board that I opened the screw holes for Mono Eye fixation at the same time.
Then adhere threaded plastic pipe to the back of the head , so that I can screw the unit of Mono-Eye.
I connecting the LED to the battery,and it looks work!
