I learned kinda how to do armatures in blender did so very badly and have clipping issues between the hoodie and the arms this model might also be hard to print also includes an uzi model in blender with a armature that kinda works but not realy at all. If you wanna fix it be my guest
The author remixed this model.
I added an armature to the model and posed it both I did poorly as it is my first time but files are included. If you do pose it better I can use meshmixer and try to make it printable alternatively follow this.
