The Hawk Eye is an attempt to replicate the Deep Space Tourbillon of VIanney Halter. Although the main design is basically the same, I adapted it to a bigger scale and a clock with only one hand indicating minutes.

Each part is printed with its own settings. Few need support but many require precision.
Be caeful especially with the following parts:
Make sure there is no imperfections on the surfaces in contact with each other.
How I Designed This
When I designed the Hawk Eye, I wanted to replicate the Deep Space Tourbillon into a fully working 3d printed clockwork mechanism. Eventually the main design is basically the same, I adapted it to a bigger scale and a clock with only one hand indicating minutes. I’ll have to be honest here, building this thing was far from an easy job. The mechanism is designed with more than 70 parts to print and 15 metal components including bearings and axis and it took me more than two months of work.
I thought about two ways of powering this clock : at first the classical way involving a weight but I experienced difficulties with firction and the tourbillon getting stuck quite often. Then I tried a more precise one involving a stepper motor piloted by an Arduino and it worked like a charm.
I invite you to read the guide I wrote to build this thing.
