I've done three modifications to the original model.
1- I've made the feet a whole thing with the base. They had space below them.
2- I've re-sculped the thumbs.
3- I've made the sword handle more thick, so it doesn't break off any more.
I've kept the two STLs.
To obtain a good sword I've printed it rotated on the back, making the sword edge pretty much parallel to the ground.
Concentric supports with interface.
