About this 3D model

A holder a bit different from the others...Feels comfy, easy to handle in action (while running, skiing,skating, diving, skydiving etc.)Please don't punch someone with it. (I tested it for you, it does what a brass knuckles does, perfectly).In some countries, it's illegal to carry or have brass knuckles, so know your region's laws. Instructions: Print as seen on render photo.I used 100% infill. It holds your GoPro so it should be durable Uses support material.
