Fontaine de billes

thingiverse

I'm a Machine à Billes system, operating on the same principle as my previous project. Four distinct circuits are employed. A central elevator is comprised of four vertical channels and a multiple step gear. Apart from a small ramp to provide an initial push, I've avoided inclines in the channels, relying instead on changes in elevation to generate sufficient acceleration for each stage, thereby slowing the balls' speed to a maximum.
