Activities for Toddler Busy Board

A set of gears, spinning wheels, and a simple maze for a toddler busy board. All screw on with #6 wood screws. 16mm M5 bolts are needed to attach the gears. 12mm M3 screws are needed for the maze. The spinning wheels require a 6mm shaft that is about (20mm + number of wheels x20mm) long. I have included a printable rod, but a manufactured one will be more durable.
