Prusa's timekeepers contest [https://www.prusaprinters.org/contest/11-timekeepers] and a little extra time off due to Memorial Day [https://en.wikipedia.org/wiki/Memorial_Day] presented an opportunity to revisit my sundial wristwatch.
Major changes that you can see include
- Making the gnomon a permanent part of the face, rather than a piece that has to be stowed and deployed
- Making the hour markers “valleys” instead of “hills”
Behind the scenes, I refactored the design to make it easier to change the design latitude. Now I just have to change a parameter in Fusion 360.
To start, I'm including
- 32⁰ (Jerusalem)
- 39⁰ (Washington DC)
- 50⁰ (Prague)
Shopping List
- The compass insert I used is https://www.amazon.com/gp/product/B0052CEFMU

Assembly
On my printer, the compass and bubble levels were press fits, but I found that if I bumped my wrist they sometimes fell out, so I used a drop of super-glue to hold them in place.
If you find you the inserts don't fit, it should be a simple matter to adjust the scale in your slicer.
UPDATE 01 JUN 2021
If you are one of the five people that has already downloaded this design, I apologize to you. I double-checked my calculations this morning, and found that I used the tangent of latitude (instead of the sine) when placing the hour markings on the dial. I have uploaded corrected files.
UPDATE 02 JUN 2021
A little more tweaking of the mounting hole for the compass to give it a tighter fit. If you're happy with what you've already printed, no need to download again. If you're frustrated that the compass is a little loose, the new files may help.
I promise (B"N) that I'm really done this time. Of course, if you had asked me yesterday, I would have said the same thing…
