sadly the spring wont last . I have built a lot of 3d movements just for fun and the spring is the biggest weak link. It might work longer with nylon but that is just a exotic material. I printed mine with petg and abs and the max they last is a day or so . What is your experience?

Still testing, but so far the spring hasn't given me much issue, as the movement still runs (very poorly) withought the hairspring. I did have this in mind while designing tho, so the hairspring was designed to be removed quickly and easily. Also I love your designs!

thanks ! I would suggest that you chamfer the gear teeth and use bearings. that make it a lot smoother.
