This case gives you greater stability while using your gopro with the gopro app than you would get with a lcd screen. The idea was originally based off of the GoPhone case, check out the Kickstarter link here: https://goo.gl/B1uCPp
Step 1: Start Out With Case
I started out with an iPhone 5 case, I have done this on many different cases such as the iPad mini, and Samsung Galaxy S5, you don't have to start out with an iPhone 5 case. I found many cases on thingiverse.com
Step 2: Add Gopro Mount
I found some models of flat gopro mounts and added them on top of, but sunk into the case. Here's just one of the mounts I found: http://www.thingiverse.com/thing:316600
Step 3: Decide How to Print
My Makerbot Replicator 2 would need to make supports to print correctly, and it would be a pain to take the off, so I chose to use shapeways, and that cost me roughly $20. Here's the link to buy the iPhone 5 case: https://goo.gl/qZhgqX, I will be adding newer phones soon.
Step 4: Getting the Case From Shapeways
This is my favorite part of it! The case fits both the gopro mount and the iPhone perfectly. I put my Gopro on Wifi mode and now have full control of it right from my phone. Don't forget to vote for me in the 3d printing contest!
Step 5: The Test
Testing if it works. It is best to have the gopro between your pointer and middle finger to have greater stability while shooting. Here's the link to the video: https://goo.gl/1Y9lfO
