This is my remix of Will Burn's Backbone case.  I liked the design but it had some issues that I thought I could improve on:

1.  This version includes a carrying handle.
2. I improved the fit between the two case halves.
3. My Backbone controller would not fit in his case with the adapter pieces installed so I widened that area.
4. The side grips for the controller were loose in his design so I tightened the fit so it would not move around in the case.
5. I added support underneath the spring-loaded cross member of the controller.
6. I added thumb grips to help separate the case halves.
7. I added tabs that hold the case halves together when travelling. 
8. I added the white outline of the game controller and the Backbone logo.

The first one or two times you fit the case halves together, it will feel pretty tight. Don't worry… once you put them together and take them apart a couple times they will loosen up.

If you don't have an AMS, it will simply print the white logo the same color as the rest of the case.
