So I got a waterproof case made by Lifeproof for my iPhone 5. The case is great but it's too big to fit in the armband I use for running. Lifeproof hasn't released a compatible armband yet so I designed my own. This is the third version (first published) of this case and I'm quite happy with it. The phone fits in perfectly and doesn't move once in place. It removes easily when your run is done. Additionally, all controls are still accessable!This adapter is made to fit the iPhone 5 with a Lifeproof Fre case. The strap slots are sized to fit a 45mm neoprene armband I had from an older case. I printed the case on an Ultimaker with blue transulcent PLA. I used 25% fill and a .1mm layer height. The file was made using AutoDesk's 123D Design for Mac. It is probably the most buggy piece of software I've ever used. I'd complain more it it wern't free!
