Industrial Automatic Punching line

Simple toy that mimics an old fully mechanical assembly line for punching holes at a predetermined distance.
It's composed by a crank mechanism, a Geneva drive and a single reduction stage with gears.

Print at least the component "Shaft_3" with 100% infill or horizontally.
