I have never tried to make anything like this before.
Its not very exact in any way, I just wanted to try...
I used it to deliver the cake for my 6 year old sons birthday.
(R2 D2 cake)
The helmet missing some stuff, like the arrows, the "mic" etc, but I will do them as soon as I find a proper visor.
The one I made was from a transparent plastic sheet and car window film, but you cant realy see out...
Its a budget build, the most expencive was the ammobelt that I bought ready, 35€ the rest is "home made"
Its not in scale or accurate in any way, but I like it
Anyway, here are some pics:
