This is the hinge joint for my DIY marble track set that can be made for less that $3. The hinge holds two track pieces and allows one piece to be angle 0-45 degrees. It also has slots for a thin piece of poster board or index card to help ensure the marbles have a nice smooth curve when coming down the hill. Please watch my video on how to build the entire marble track set.
