PLEASE DON'T USE THIS UNLESS YOUR DESPERATE
ITS NOT GREAT AND THERE ARE PAID OPTIONS
THIS IS FINE IF YOUR JUST GETTING STARTED
These are speedcuffs that are used my most British police. The speed cuffs used to have a high polygon count. I have decimated them so they can be used. This is meant to be used Blender and be UV edited but you can use any other 3d modelling software. You are gonna have to do the textures as the file did not come with textures.
