3D printed: mechanical counter

This is a simple, easy to build, three digit mechanical counter. We're using a stepper motor and an arduino to control the counter as well 3d printing all the necessary parts.

other things you need:

Arduino (I'm using a MEGA)

28BYJ-48 stepper Motor

10(1/8x3/4 machine screws) and two nuts

3/16 steel rod - 2 1/4

3/16 steel rod - 2 3/4

note: there are two different number wheels two of them have pegs and one doesn't. make sure that the to plate in installed correctly.
