Well, now I have a better idea of just how detailed an item my 3D printer can print.
Old (30+ years) Mac floppy drives have a tiny eject mechanism gear that becomes brittle. You can find a design for this gear that allows printing them.
My resulting gear was way too low-resolution for a gear this size, sigh.
Time to buy one.

@donm This may or may not be a useful tip, Don: try your local library. Ours has 3D printers that cost several thousands of dollars each. That can print down to 0.06mm granularity -- far exceeding most home 3D printers.

@donm what size nozzle are you using? You should be able to print finer detail with a smaller nozzle, but there is still a limit to how small you can go. 0.2 mm is a common smaller size, and is half the size of the more typical 0.4 mm. There might be 0.1 mm nozzles you can find too, but those are not as easy to find.
