220 Clock Model

I modeled this design after a Urwerk UR220-SL watch. It has been scaled up to be a wall clock sized version.

NOTE!
Before starting the project, make sure that you get the correct motor. There are several Chinese sychronous motors on Ebay and Amazon for about $12. They look correct, but do not work. They claim to be 1 RPM, but they are not exactly, so the clock will gain a minute or two every day. You need to use a replacement motor for an Acroprint 125 or 150 model Time Clock.
It's not cheap, but it keeps perfect time.

This model is LARGE, at about 236x232mm. My printer has a 210x210 print bed, so any parts that are too large for to print on my bed are also available in 'right' and 'left' half STL files. Also many parts are available as sets of files that can printed on printers with a multi-color capability.
And it's powered by an 110V AC Synchronous motor.
