  • Geared mechanism converts normal clock movement to a world clock with automatically rotating world map.
  • The world map rotates at live speed (1 full turn per day).
  • You can operate a time zone dial to confirm the current time at any place in the world.
  • When the dial is at the home position, you can see the area of daytime (bottom half of the map) in the world.

credit:

3D world map is derived from the data "Elevation World Map" by Domi1988, at https://www.thingiverse.com/thing:3691537

His data is deformed and scaled to round shape by Blender. Thickness is changed from 5mm to 4.2mm, so please modify the value of "height at pause" function if you use multiple colors. It would be better to test with small piece (scaled to X and Y axes) in advance.

Appendix ========

The gear (herringbone planetary gear) is exactly same part to the thing "Perpetual calendar with mechanically automatic day of the week", https://www.thingiverse.com/thing:4639361

except the scale (60%).

You could give realistic colors to the map using multiple materials. Please take a look at the make of original map data,
https://www.thingiverse.com/thing:3691537
and its make [https://www.thingiverse.com/make:719141](/make:719141)

Please be sure that the height of the object is scaled from 5mm to 4.2mm.
