These mechanisms are tremendous factor in assembly and packaging. So, there has to be specialists in vibratory bowl feeders, right?.
With slightest degree asymmetrical, doesn't seem any limit to what will feed and sort. Screwdriver bits, tacks, screws and nails, cartridge cases, bottle caps, rivets, brackets and other stampings..., large or small. Many in use long before CAD drawings, CGI, or any type of virtual electronic imaging.

So, what kind of hardware littered desks of these specialists; toying with how to feed so and so?
Not everything can be solved with just a cocktail napkin!
