How I Designed This

How the marble maze was designed in Tinkercad

            <div><p>I started with a 19mm cube, and tapered each edge.  I assembled all 27 cubes into a 3x3 cube and set to the side.<br>I designed the holes and tunnels with cylinders and spheres, rotating appropriately to make 90' turns, straightaways, and T intersections.<br>I grouped all the tunnels together, then aligned them with the 3x3x3 cube</p></div>
