Mazinger Z with movible arms

thingiverse

this is a remix in wich i make the arms movible. I modified it in tinkercad, i'm not expert in making joints so this is a rudimentary idea but it worked just fine. Notes: 1- probably you will need to sandpaper a little some parts in the arms and in the hole in the mazinger's body. 2- i do not why but when i imported the original stl file into tinkercad some parts where damaged (the helmet, that i try to fix, and the shoulders, i noticed a flat area after i printed, but it is almost like if it was a part of the piece)
