The Laputian Robot Trooper (WIP)

Wanted to make this one for me. The guardian robot from Laputa from Castle in the Sky (1986) from Studio Ghibli. I am attempting something else new, The arms will need to be connected and this should give them a flexi arm style. I'd love to do the arms in a print in place but I don't know how to do that. 

I again don't know how to size things in my files. I am printing at x150 in my OrcaSlicer. It's printing currently. I'll update when I have something good to show.
