Tripod Mount for iPhone 6 Plus with Thule Atmos X3

thingiverse

It allows you to keep your case on the camera and utilizes the rubber-ness of the case for a snug and secure fit, without undue clamping stress being placed on the iPhone itself. For mounting iPhone 6 Plus with the Thule Atmos X3 case. Snugly wraps around the case and provides 3 x 1/4-20 mounting options. The part is a bit bulkier than it needs to be, but it was designed to print well, it's solid and will hold your iPhone securely. If you don't have this Thule case, this will not work for you. But this case is highly recommended, well worth owning if you need a case anyway. It is most secure when mounted on the center of the camera as it is widest at the center, but will be still usable if you only push the mount about 20mm up from the bottom.
