I separated the two arms so I could print them separately, plus I cut the main body into 4 parts as the two halves was going to take over 20 hrs a piece to print. I like to keep my print runs to 10 hours or less if I can. If something stuffs up in the middle of a huge print, it's a real waste of time. I added holes and pins to the sections so they could be easily located/lined up during assembly.
I sliced/printed at 70% of original size as I didn't want it too big. I printed it in grey and painted it gold. It still needs another coat of paint.
