Octopus Stand Version Three
Version three of the Octopus tablet stand. This one was designed to fit the iPhone 6/6 Plus, iPad Air and a slew of Android devices. There should be just enough room for a case with most devices. I recommend adding a little bit of sticky adhesive to the bottom to keep it nice and secure.
Note: the Moto X 2014 is pretty wobbly in it and I would not recommend it at this time.
I've printed a copy of this out at Shapeways myself, as I am absent a 3D Printer :( You can find it here if you're in the same boat as I.
