A pipeline that turns any of ~8,000 lift-served ski areas on Earth into a watertight, 3D-printable STL. fetch_resorts.py scrapes OSM Overpass globally (landuse=winter_sports + aerialway lifts) into a single catalog; selecting a resort auto-pads the bbox, fetches AWS Mapzen Terrarium PNG-encoded elevation tiles in parallel, decodes them, and stitches a single-band float32 GeoTIFF. A three.js viewer lets you trim with rectangle, polygon, or cut-line tools, then download the STL or a multicolor Bambu Studio zip with one watertight ribbon per piste difficulty class and lift type.
