Hi Erick! Your design to modify the belt clip is very cool. We wanted to reach out and let you know about our uniVERSE Case System which allows you switch and swap accessories onto the back of your phone. Better yet, now you can design your own accssories for the system. Head to www.otterbox.com/universe-cad to find out more and download CAD files to get started. Thanks for being an OtterBox fan!
