K'nex Counter

This is a counting machine the can count from 0 to 99 I got the idea from the ball counter NorthernF made.

Let's get started.

This is the base and one of the walls.

Attach the motor to the part in the last step.

The wheel is the hardest part because it has ten sides. The numbers are printed and glued on but you can also tape them.

Attach one the wheels on the wall and put the other wall on.

This is the gear that spins the wheel on the other side. Make sure that the gear and wheel are positioned like in the picture.

This is the gearbox of the machine. if the numbers spin backwards add another gear.

This is the other wall and wheel.

Add the roof and the side that shows the numbers then you are done! Have fun counting :)
