Skull Crusher Battle Axe

I made this axe using 3ds Max. I have only ever printed a small scale version which about 9" but would love to see full size (3' or 4') as a cosplay prop. I don't have a ton of modeling experience so I am unsure how to cut it into smaller printable pieces. I would love to some see remixes too.

I added supports and a raft but think it could potentially be printed inverted with the blade facing down.

Please upload a photo if you printed this, I would love to see it!
