Oxigen Tank page.
I called it
"Oxigen Tank" because I don't know it's original function in the film so I
gave it a name for reference.
And here is my
"version" very very enlarged. The size i 11,4 mm diameter.
I made it using special plastic cap used for plants drop-irrigations.
The overall diameter and external aspect seems to me the original can be seen into the film.
Not too much
work on it. Only cut to reduce the height and painted it.
I made it in two samples to have one more choice to rely on.
