Originally I intended on truly remixing Sunny_print's model to move the mechanism to the centre, as I felt that was more fitting for a wall clock.

However, when I tried that, my slicer wasn't enjoying it, so I started from scratch.

Every part of this has been designed from scratch (with heavy inspiration from Sunny_print), other than the second hand, which fit as is, and I kept original.

The design has also been adjusted to incorporate a threaded mechanism, as I wanted to install a radio controlled clock and the only ones I could find were threaded.

I used this mechanism: https://www.amazon.co.uk/dp/B07SPCBZV1

The pin from the second hand pops off quite easily, and the printed second hand was a perfect fit for me.

The other hands may need some filing for the post to fit correctly, or you can try to scale them up a couple of percent.

I filed the hole in the faceplate slightly, and screwed the threaded part of the mechanism in to it.
