CGI accurate Iron man mk5 helmet comes complete with full faceplate and jaw motorization as well as the first ever ear motorization in this style of helmet. also has options for full interior details and options for no interior details. The motorization arms also have heat set insert motorization where you use m3 threaded brass heat set inserts to screw the motor arms together

in terms of programing the motorization of the ears, crashworks has a board for the walsh3d mk85 that also works for this, though you may need to change some degrees in the code. if you don't want to motorize the ears then the normal crashworks board should work fine, or you can use a normal Arduino nano and just use their code for either way you want to motorize it.

I have lots of other really high quality 3d printing models for same so I would appreciate a positive review if you liked the file, and also I have an instagram where you can buy directly from me, and I even have some free models for my followers, so go check me out @levy3d I have some models there that I dont pst here that you may be interested in :)
