This is a mount for an Amazon Fire 7 Tablet ($50 on amazon). I've found it much easier to use the OctoRemote app for controlling the printer rather than navigating through the LCD Menu (especially comes in handy when adjusting the z-axis). Plus all of the files on the octoprint server are accessible right from the tablet, ready to print.
To Install:
To get the tablet ready (I did this before mounting the tablet) -
Install the google play store on your tablet (I used this tutorial):

Once the play store is installed, search for and install octoremote:
https://play.google.com/store/apps/details?id=com.kabacon.octoremote&hl=en_US&gl=US
After the app is installed, fill in your OctoPrint Server address & API key, and you have control of your printer!!
