Hey guys! There is an updated version of this that is much more robust. Check it out on my page!
This mount is designed to work with any iPhone since the 5. I have personally tested it with the 5, 5s, 6, 6s, 7, and the iPad mini. It is extremely easy to use and holds your phone securely. Because of the spring style design you can even use this with a thin case or bumper. I have uploaded two files, one has a cutout to insert a .25" - 20 nut while the other file has threads printed directly into it (for those with very precise printers). Also, please only print this using ABS due to the reliance of its elasticity.
Thank you for checking out my design! I would love to hear you guys' feedback.
Treating your print with acetone may make the spring stronger but is not necessary.
Infill isn't a huge deal either- i printed one at 80% and another at 50% and they both work fine.
