About this 3D model
This is a remix of makermichael's Iphone 5 Lifeproof Armband. It was a little difficult to get my phone to slide in and fit, and the strap slot positions were not to my liking, so I added chamfers and radii to the side arms, as well as increasing chamfers on the bottom arm. I also put a radius all along the bottom edges so it would not cut into my arm when strapped in. I also included the SolidWorks (2012) file to play with. Have fun all!
