About this 3D model

Lots of fun on the front of your refrigerator! These pieces can be put together in an infinite number of ways and the marble may (or may not) make it all the way down. Try racing games, or see who can take the longest to get down. Just print these at .3 layer height 10% fill. All you need then are some standard 16mm marbles and some stick on magnet sheets from your local hobby store. Many more piece designs are possible - I would love to figure out a loop-the-loop. check it out-
