how long do you think it will take to laser cut a couple tiny gears ?
seconds.

And you're still in inches. You haven't even lined the rule up with the tip of the bottom gear.

Aaarrggh.

Do you have a set of digital calipers ?

If so give me overall diameter, thickness and the diameter of the central hole.
With fewer teeth I don't actually see a huge problem.
I've printed smaller things.
The trick is to print several at once.

I can knock out a parametric gear file in openscad, no probllem.
But not without proper measurements.
