This tactile and delightful looking mechanism is a planetary gear. So named for the four planet gears orbiting the central sun gear. I've put this project together as part of my learning-to-use-a-laser-cutter experiments. Instagram LinkEmbed by embedinstagram.com
The parts are all laid out in a pdf file and then transferred to the Laser Cutter software. The downloadable file is available as a link in the previous step. I've left it as a pdf file as, if you have, or have access to, a laser cutter then you will know how best to convert it for use on your particular machine.
