why not print roller chain? print plates(same for inner and outer links) and bushings. pins would be plastic filament. you could forgo the string and just print simple parts with no spacing requirements, some assembly required though.

the issue of maintaining perfectly even spacing between gears is an issue. One idea would be to make it so that you print the pieces in sets of 5 or 6 and each is printed with a thin (maybe 2 layers) surface connecting them(just a string of plastic really). That way, you could attach the string as you describe (though I think two small sides that snap/glue together would actually be easier) then simply snap the thin connectors away. You could then be assured that there is correct spacing between the bars.

You would need to print past the holes first as the nozzle would scrape any string off the table unless its recesses already. might design it as two snap together shells.?

Yes ill address that in an animated illustration that i will post soon. by printing the bottom half with a narrow channel, then adding the strings, and finally print the top half
