I designed this stand for my iPad 2, which has an Otter Box case. Some of the stands out there don't seem to allow room for the added thickness of a case. It works fine with a Nook or smaller tablet as well. It's 4.75" (120mm) wide. It allows the tablet to sit at about 30 degrees or 60 degrees (portrait or landscape orientation). It is pictured as printed with ABS in 3DPrinterNinja Dark Blue. The Triangles Tablet Stand makes a great gift item, especially for people who aren't squares.
