-I saw some working 3D printed clocks and became fascinated with the idea and history of clock making. There are multiple publications of makes and 3D designs out there that can be downloaded and assembled, but they all lack the details that I wanted to understand and these are not described in the detail that I needed to understand. Also the terminology in horology literature is unfamiliar and now always clear.+I saw some working 3D printed clocks and became fascinated with the idea and history of clock making.

 +The gear shafts are cut from any 4mm round rod material. I had some 4mm steel wire and searched for 4mm bearings to go with that.
