We just fixed downloads: every STL now comes straight from fast, reliable storage, saved under its own name, we're making 10,000 STL files and dozens of new tools, so things might break. We'll fix them ASAP.

STL Sundial Generator StarForge 3D Modeling Software

Garden Sundial Set to Your Town

A sundial only tells time when its gnomon matches the local latitude, which is why the STL Sundial Generator starts with a town found through OpenStreetMap place search. It sets the gnomon to that latitude and spaces raised hour lines by tan(angle) = sin(latitude) x tan(15 degrees x hours from noon), on a dial of typed size. STL, the Stereolithography mesh, then goes straight into any slicer. StarForge 3D Modeling Software downloads a 3D Print STL File for 3D printing a garden or patio sundial that reads true once pointed at true north, or true south below the equator.
