About this 3D model

We have purchased several phone holsters for our two Samsung Galaxy S3 phones because this part keeps breaking. We have tried different brands, and they all suffer from the same weakness. Now I can just print a new one when it breaks next time. The pin holes are less prone to breaking because they are wider, but this also means that you have to push the pin in a little deeper to get the fully effective hold.
