Hi,
Can some one help me to find for orion v3 replacement parts (silicon positive insulator,top caps, Small metal Screw and Spring that ride on positive insulator, etc)
Here you are. Not sure of they ship to Saudi or not, but the parts are the same. I did not look for the screw. Not sure of the screw size either, it is maybe M2, or M1.4. I am sure someone else will chime in for you on that one.
