01Go Is A 3D scanner that fits in your pocket. The pen-like device simply rolls over whatever you want to scan & collects data on that object’s shape & dimensions. The data is sent to an app in real time & you can watch as the 3D object is drawn into the app. Whether you need to know if a piece of furniture will fit in your space or want to “borrow” a design you see while shopping, this little device will come in handy.
