Remix of Super Simple 2x Digit Counter V2.8!

See https://www.printables.com/model/3176-super-simple-2x-digit-counter-v28 for all details and models. This model replaces the core of the original. It makes the spinning bidirectional; both ways have the same resistance. That way it is more suited for a generic counter and not just a spindown/life counter. It does have less of a clicky sound because of the change.
