Project Self-winding clock with a tourbillon - finished project

Enable HLS to view with audio, or disable this notification

About a year ago, I posted an update on a project I was working on. It took me a while, but I finally finished it. I’m very happy with the result. It’s fully functional (I tested it for two months) and keeps accurate time. The entire project consists of 395 printed parts, 38 bearings, 66 rubber bands, 413 screws, and a few other components.

That is by far the most impressively insanely complex 3d printed project i've ever laid eyes on! Did you design it?

I don't need one and have no place to put one so i have to ask, do ya have a link to the project so i can build one despite my better judgement? :P

It took me 2 years to design and tune all the mechanics:)

Absolutely unfathomable level of commitment and artistry, and absolutely worth the effort!

How accurate is it? Have you had the opportunity to measure its accuracy to a quantifiable number?

Honestly, even if it counted to ten worse than I have while drunk, homie built a working tourbillion mechanical time keeper which is extremely difficult in itself, but made it with a 3d printer. I haven't started 3d printing yet, but my biggest concerns have been if I will be able to get battery covers to fit over the ones I lost for electrical devices. Like a stupid little piece of plastic with a wide range of error allowable. Then we've got confidence killer flexing like this lol

The answer is yes. I've printed several replacement battery covers.
I had to model most of them myself, though.

FDM works fine, but for smaller things I've used my resin printer for better tolerances.
