You can easily search out an available iPad stand for your iPad mini and iPad Air such as, but if you have a 3D printer, you may like to make an iPad stand by yourself.
Martin Hajek, a talented designer (have you remembered his iPhone 6 design concept?) created PadFoot, a simple yet practical tablet stand for iPad Air and iPad mini. As shown in the images, the iPad stand features ultra compact design in order that you can put it in your pocket or bag for portability, and its custom groove is wisely placed at the end of the kickstand in order to support both portrait and landscape viewing modes. Moreover, the designer has released two highly PadFoot 3D model files for iPad mini and iPad Air. If you’re interested, get them from Martin’s website, and making the stands using your 3D printer.
