Friend of mine wanted to play an aarakocra barbarian and since Mz4250 had not made one yet (one with a greataxe anyway) I re-positioned the hands and inserted the greataxe from his Molydeus weapons.
Added in version without base that uses less filament especially if not printing standing up. I printed mine at an angle to reduce supports on wings and print axe more level.
I took Mz4250's base aarakocra and using Blender re-positioned hands to be holding a two handed weapon. Then because wings and legs got messed up (not enough bones in Blender) I merged the old and new torso together. Then scaled down Mz4250's Molydeus' axe and positioned to fit in hands (Note: only one hand is open so you can't print axe separate).
