Thank you for the feedback 😊
Dave,
I did cheat a bit on this! The model of the clock was downloaded from McMastercarr in Fusion360.
There were a few alterations needed to the model to all it to be printed and then everything had to be scaled to fit my 3D printer. The clock face took some finding as I needed a highish resolution picture of a Mitutoyo DTI face only (it had to be Mitutoyo to complement my large caliper clock). Finished off with a click mechanism from Temu.
