Damn it ! it's so cool man :O !
Great job !

Anyway how much cost your video glasses in your helmet ? i would do the same for mine but i can't find it ^^

It's Marvel's IP - no matter how much time I spend on it, it will never be mine to sell.........

Your build is looking amazing already even without any finishing and a huge thanks for sharing the STL's with the community.

Do you think you could make the sliced files available also?

nice...(I see the use of Neopixels for the eye.. (hence your +5v!) )


what video goggles are you using?
