iPhone 5/5S case/bumper

I designed this case with the idea to still be able to see the nice back of my phone, and because i was bored. To apply the case, simply press the big part over the phone, and hook up one of the sextants from the small part to the big part and pull it over so the other sextant snaps into place. I haven't received my printer jet so i didn't had the chance too it print myself to see if it works as well as I hope
