This is a wall mount for a tablet or phone, specifically designed to fit the Sony Xperia Z3 Tablet Compact. This will work for other tablets or phones that are less than 8mm thick. with a 6mm or greater side bevel. I made this mount for use in the shower, but it could be used on any wall.This is designed to print upwards as the file is oriented. the holes for the hooks are 5mm in diameter. If you are mounting this on a slick surface such as shower tile or glass, I would recommend these cheap and good quality suction cups: http://www.amazon.com/gp/product/B000FA6CIE This mount is thicker on the bottom than the top so that the tablet leans back against it. The protrusions on the bottom back part are to hold the bottom of the mount out far enough from the wall. If you use other hooks than the suction cups linked here, make sure they don't protrude from the wall more than 14mm. Remember to use all three hook holes so that your tablet remains on the wall in case one fails, especially if using suction cups.
