Galaxy S5 gun mount with otter box

This a mounting using the belt clip from a otter box that's screwed on it. Basically you need some bolts and nuts, the main frame et the side panels. The picatinny attachment can be printed or it is possible on many rail system to simply tie wrap the frame. I've printed it and played a few games with it on my gun using a printed picatinny. It's ok but I don't like the screw on the otter box clip, it's putting to much stress on my phone. Need to rethink the main frame attachment.
