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.

GLB Sundial Generator StarForge 3D Modeling Software

Sundial for Your Town's Latitude

A school science project or astronomy club page can show its sundial in the browser as a GLB, the binary glTF file model-viewer, three.js and Sketchfab display without plugins. The GLB Sundial Generator makes a horizontal dial for a town found through OpenStreetMap place search, with a gnomon angled to the local latitude, raised hour numbers and hour lines calculated as tan(angle) = sin(latitude) x tan(15 degrees x hours from noon). The dial size is typed. For 3D printing, StarForge 3D Modeling Software saves it as a 3D Print STL File that reads true once aligned.
