About this 3D model

Hi everyone! This is my submission for the Gopro Mount competition!I created this for a school project and have a full write of (with pictures, build log and more) down below: https://goo.gl/M7HXRU <----- opens in a new window :) But the TLDR is that this is ment to help sound when using the gopro by using rubber bands (much like a shotgun mic). As we know one of the selling points of the hero 4 is that it has a good mic, well thats kinda runied when you can't hear what your saying because of your hands baning the handel right!
