Let the dominoes fall! Everyone loves domino tumbles, and setting them up is super easy and fast with these pre-racked tracks. Even little kids can do it - turn a piece over to swing the dominoes into place, and line them up for a chain reaction. Curves and forks let your road run everywhere!Dynamite Dominoes are simple to build and assemble:Accompanying .stl files provide the basics. A .zip file includes plates with other awesome domino-track combinations, along with SketchUp sources to let you customize and put together the perfect kit!Printing Tips - I get excellent results printing the tracks at 10% fill and the dominoes at 25% fill (to give them some mass), with one extra shell. However, I recommend doing a small test print to make sure the pieces fit correctly before moving on to bigger plates.
