iPhone 5 Bumper For Fraemes

I created this bumper for the iPhone 5 that has groves in the bottom for the Fraemes inserts. I'm using the NinjaFlex filliment to print it on a MakerBot Replicator 2. Based on the Fraemes insert design (a fantastic desight by the way) I thought I would create my own. All kudo's to Fraemes.
