I am late to the game, but I got my first 3d printer(Ender 3 v3 SE) a few weeks ago and immediately jumped down the rabbit hole of building my own Spartan, I am going for Jai-006 of Grey Team, armor which I believe is mostly Mark V(b) armor, with the air assault helmet, Operator left shoulder and MK V right shoulder, if there are other variations I am missing I'd love to hear about it. I got my friend who had a much larger printer to do the helmet in one go, and it will fit great with some padding, I've also printed the hand, forearm, bicep, and shoulder pieces and now starting from the feet up. so fair only a couple of failed prints, and some weak parts that snapped due to poor banding on my printer, but my scaling has been right on, and I look forward to getting started on the larger pieces and slicing them up and putting it all together in post-processing! Any tips or critiques are appreciated!
