Rainbow Stepper




Steppers as a main module are very common in the Great Ball Contraption world but I did not have one. So I designed this stepper with 22 steps controlled by a central axle resulting in a simple and reliable module.

    Sweet, I haven't gotten into GBC yet, but your designs make it seem like they are pretty easy.  Thanks for sharing.

    Beautiful. Another rainbow, this seems simpler. We will have to start looking for pieces in BL. Thanks, Berthil.
