Customizable Horizontal Sundial. Use Customizer to specify your location and give your dial a custom label! Note that the dial is corrected to read in Standard Time for your Time Zone.
Caveat: This sundial is designed for the Northern Hemisphere. I have no clear idea how to adapt it to the Southern Hemisphere yet. When I figure that out, I'll post a Southern Hemisphere version.
The Horizontal Sundial is easily customized to your location. Start by finding your latitude and longitude (in decimal degrees) here: http://universimmedia.pagesperso-orange.fr/geo/loc.htm
Longitude may be positive or negative; Latitude will be positive. (Otherwise you're in the Southern Hemisphere. Refer to the Caveat above.) Note you must indicate both your exact Latitude as well as the range of your latitude in degrees. This because of an OpenSCAD limitation.
Then find your time zone correction here: http://www.timeanddate.com/library/abbreviations/timezones/ There are many different names for time zones. At the site, simply use Find in your browser to look up the correction for your time zone.
Now use Customerizer to enter your data and make an awesome custom sundial!
Note: Although there are other sundials on Thingiverse, this one was created from scratch to be customizable.
