iPhone 5s Impact Case

This is a case I designed because all other cases on thingiverse dont seem that protective of the screen. This case is made with 2 parts that screw together. Version 2 is coming soon with o-ring spacers to take more impact. I thought that the lower the amount of infill the more resistant to drop damage but would cause more damage to the case itself. I encourage anyone to edit this so that its design can grow. Thank you
