Earlier this week HODINKEE published a fantastic article on how an engineer, and watch enthusiast, created a model of a working tourbillion watch calibre for 3D print. What was great about this maker is that Laimer put up all the schematics up on Thingaverse and Autodesk 360.
I have always admired the engineering and design work that goes into a tourbillion mechanism, and yet never fully understood how it worked. With Laimer’s files I plan to. There is about 50 parts to be printed as well as the need of some shafts, screws and washers.
I am surprised that PLA can be used to create a working hairspring!
