This is a mechanical watch with tourbillon and going barrel. The watch has a Swiss lever escapement, embedded in the tourbillon. It is driven by a 3d-printed spring, and runs 35 Minutes (a wire retraction spring made from steel would perform better). My watch is running with less than 0.5 Seconds deviation within one Minute.
The project demonstrates that the 3D-printing technology is developing. Compared with earlier generations of 3d-printers, the process works more reliable and more accurately.
The watch is designed with Autodesk Fusion 360, and printed with Ultimaker 2.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
