iPhone 6 Plus case with elastic strap option

I got tired of my iPhone 6 Plus feeling like it was going to fall out of my hand so I made this case(2mm wall thickness) with an elastic strap. The strap can be moved left or right for better grip. When the strap isnt used it lays flat and out of the way. Enjoy!

If you want the same case without straps you can use my other design here: http://www.thingiverse.com/thing:541513

Update 11/14/2014:
Added two thinner walled versions(1mm and 1.5mm). Original version is 2mm wall thicknes
