Bring your guard dog to the shelter, because i have made a cheaper and better (but also less dangerous looking) alternative!This 3D model is a vehicle for the Sphero, but not just a normal one. You can mount you GoPro camera on it, so you can track your Sphero live via your Smartphone or tablet.You only need a Sphero (app-enabled ball that will move at your instructions), PLA and a 3D printer to print the .stl files.You will dowload 2 files, the Base and the wheels.If you like this model, also take a look at these two:https://www.youmagine.com/designs/sphero-canholder-vehiclehttps://www.youmagine.com/designs/sphero-canholder-gopro-vehicle
