I basically took a basic iphone 6 case from https://www.thingiverse.com/thing:471548/ and took the design from https://www.thingiverse.com/thing:821574/ because a patron from the library came in asking for an iphone 6 version. I have not tested it yet but hopefully it fits. Please let me know.

Edit:
I printed it and it fits a coworker's iPhone 6 perfectly and looks great.
