Hello!!, If you are a Naruto and ninja stuff fan this short instructable is for you. Just download the .stl file on the link below:
Now upload the .stl file to your printer program and print, you shouldn't need any modification of the .stl file. If you are going to print with abs make sure to spread some hair spray on the heat bed.
And that's all folks, if you have any doubt or problem when printing you can ask for help on the coments. I will be happy to help you. Happy printing!!
