Microsoft already has a docking station available for the Surface Pro 3, but it only allows the 12-inch tablet to be used in lanscape mode. Today, as part of its Microsoft Garage program, the company has released files and instructions to create the 3-in-1 Dock, which will turn the current docking station into a portrait VESA-mounted dock for the Surface Pro 3.
The project, which was first demoed during Microsoft's Build 2015 developer conference, does require that the maker have access to a 3D printer and a laser cutter to help create the parts needed to put together the 3-in-1 Dock. It also requires that the user open up their Surface Pro 3 Docking Station, which will void its warranty. Once the DIY project is completed, the dock will allow Surface Pro 3 owners to use the tablet in portrait mode on the same eye level as their regular PC monitors.
