I've been interested in gear transmission for a while, and decided to play around with the idea using laser cut wood. My original inspiration came from this project on thingiverse, which I adapted into what you see in the second gif above (and fifth + sixth images above). I found the spinning gears really calming to watch, and made a few for friends to keep them entertained at the hospital or when studying for exams.
Since they were quck to design and easy to personalize, I ended up building my own gear trains and cutting out a few as early holiday gifts. My friends really liked the pleasing "clicking" sounds as the gears mesh with each each other so I decided to explore with more designs and share this tale: in which I make great toys to fiddle with.
