This is a simple mounting bracket for the Microsoft Surface RT. Just print two of them, screw them into the wall (I used a washer to help distribute the load) and slide in the tablet. With just two brackets, the tablet is still quite flush to the wall and stable (and you can still take it off!).

I printed on medium using my replicator 2 with supports. The supports came off nicely and then I just screwed it into the wall with a washer to make sure the piece didn't crack.
