Iron Man Mark 85 Bust + Wearable Helmet - Avengers: Endgame

[UPDATE] (29/06/19) - Added files with channels to support LEDs - the 'LEDversion' files feature a hollow base and channels leading up to the eyes + arc reactor.

Here's Iron Man's mark 85 armour from Avengers: Endgame!
The inner width of the wearable helmet is about 17cm, and the final height of the bust once assembled is 15cm tall.
I was running into a few issues whilst trying to repair the torso files, however it seems to slice/print fine using Cura - if anyone has any issues please let me know. :)
