I searched the 'net (mostly Thingiverse) and can't find any STL or SCAD files to make this. I'd be interested in stacking sections to make a longer model as Frank suggested to see if it can move round things - not dough balls coz those go right in the oven!
I call this a "transport gear" arrangement but a search of that term turned up nothing, nada, zip!!
So, all I have left is a somewhat mesmerizing video to look at while my wife snaps her fingers in front of my face to steal my attention.
The more I stare at the video in the OP, I'm less convinced it would behave as a good way to transport spherical objects. Maybe it would, but I'm getting disoriented from staring at the video too long! lol
What I was intitially thinking was what I'd seen in an episode of "How Its Made" that illustrated glass marbles beinge shaped from blobs of molten glass dropped between two rotating auger-looking pieces.
