Fully mechanical binary counter that can count up and down. It's modular so you can extend to whatever digit you want.


Update 04.07.2024

I modified the bases, connectors, handles and added a lock to the left side to enhance the design durability.
I modified the one_side part to support bidirectional functionality.



In order to make a one “component”, you need

zero_side x1

one_side x1

zero x1

one x1

carry_piece x2

connector x1

For Base:

mid_base x(# of components - 2)

left_base x1

right base x1

handle_connector (print with support) x1

lock (print with support) x1



Then you can add them together and finish the build with handle. I'm leaving this assemble so everybody can play around with.
